[00:06:24]So tatangila competitive examination for recruitment to the post of storeke keeper under food civil supplies and consumer affairs department. So government of misorum April 2026 and this is question booklet series ah paper two and these are the questions. Question number one WhatsApp and horiculture LDC in an interview in Rala. Okay. Okay.

[00:07:20]Okay.

[00:07:21]this side.

[00:07:25]Now question number 51.

[00:07:27]the value of 1.99999 Dash in the form of P by Q rational number because Q is not equal to zero are integers and Q is Q is 11 value P by Q where P and Q= not equal to zero are integer and Q is Q Arew 1.99.

[00:08:10]So continuing number train like this 1.9 bar. Okay. So 1.9 simplified form 1 + 9 and number.

[00:08:29]So 9 1 + 1 is 2. So two is correct answer.

[00:08:39]Okay. to correct answer and to rational form for two by one and two by one Q is two language Q is Q and P by Q form Two correct answer. Okay. Two is correct answer. Now question number 52.

[00:09:18]1 by <unk>9 -<unk>8 is equal to rationalize denominator number for that trick unqu directly answer a radical in the uh numerator ator plus roo<unk>8 conjugate direct conjugate.

[00:09:55]Now roo<unk> 9 value is three and roo<unk>8 is 2<unk>2. So option C in answer WhatsApp group.

[00:10:19]total five free groups are there. So okay now question number fifth tree after rationalizing the denominator of this one. Okay, we can rationalize we get the denominator is one more 7 by 3 <unk>3 - 2 <unk>2 rationalize rationalization YouTube IN you will have the uh idea how to solve this type of questionjugate and same values but a conjugate now because denominator so denominator how we can solve 3<unk>3 a 2<unk>2 b 3<unk> t 3 a 2<unk>2 b a - b into a + b a - b into a + b a square minus b square now a i 3 <unk>3 square minus b i 2<unk><unk>2 a square solve 3<unk>3 square means 3 3 * 9 9 3 * 27 minus 2<unk>2 square 2 square is 4 and <unk>2 square is 2 so 4 into 2 8us option D is correct answer okay 84 forucation.

[00:12:40]Okay. Question number 53 number and for you question number 53 question 19.

[00:12:59]Okay.

[00:13:08]Okay.

[00:13:10]It is okay.

[00:13:13]Uh 1 / 2 bracket 3 - 1 / Please confirm like okay plus more.

[00:13:47]Yes. Thank you so much. plus solve 1 by 2 - 5 by 2 LCM is 2 1 - 5 is -4 and so 2 and 2 + 2us 2.

[00:14:17]So 1 + 2 into - 2 1 + -4 1 - 4 -3 option C okay 54 oh 54 it's correct answer will be confirm Answer - 3 1 by 2 - 5x 4 means uh 1 - 5x 2 - 4x 2 - and minus minus plus definitely and plus is and bracket 2. So 2 into - 2 - 4 and 1 - 3 is correct. Vboardus is correct answer. Okay.

[00:15:29]Now question number 55 here. On simplification this one what will be the answer?

[00:15:47]0 0 0 3 0 0 - one 0 + 1 0 0 - 3 so - into minus plus cancel option a Okay. Option A.

[00:16:23]Okay.

[00:16:24]Oh my go Okay. B either A or D can answer.

[00:16:48]So 50/50 at least 50/50 in.

[00:16:54]Now middle term split factorization.

[00:17:07]x + 2x + 3. Okay. Divided by and y split 3 into one. 3 - 3 + 1 or so 3x² - 3x + x -1 into as it is x - 1 2 into 3 6 - 6 - 6 + so 2x² + 3x - 2x and topa minus tri like this.

[00:17:48]Question number 17 middle term split now 3x.

[00:18:04]So 2x + 3 + 1 2x + length 3x -1 + 1 x -1 x -1 square x 2x + 3 -1 2x + 3 a now common 2x + 3 2x + 3. So 3x + 1 2 x + 3 and y 3 x + 1 x -1 into x -1² by x -1 2x + 3 or cancel x -1 in m² x -1 and x -1 are gone 3x + 1 and 3x + one gone and 2 x + 3 and 2 x + 3 gone. It means one proof 100th person. Okay. Uh question number 56 simplification.

[00:19:31]Pokemon upcoming examination means hint.

[00:19:57]because and post 56. Now question number 56.

[00:20:09]LCM of 3x² obviously 3x² + 9 x + 6 and x² - 3x - 10 3 into 6 so 3 and 3 6 3x 3x + 2 + uh 3 x + 2.

[00:20:44]3 x + 3 and x + 2 x + 1 and x + 2 for the second case x² - 3x - 10 and number - 5x 2 So x common x - 5 + 2 x - 5 common x + 2 x - 5 Now these two are common only x + 2 common all the so x + 1 x + 2 and lcm only common factor.

[00:21:49]So if your answer is B then you will get the marks. Okay.

[00:22:00]Uh just practice economics. So economics.

[00:22:18]Okay.

[00:22:26]Now BIC HCF HCF X + X oh X2.

[00:22:44]So HCF always common and LCM and remaining.

[00:22:56]Now question number 57 here. 57 mark price of selling fan is selling fan is$,750.

[00:23:05]Anya shopkeeper allows a discount of 6% on it. So 6% discount on each one. Still 9 94% Z 2 in 47 time 2 in 5 in 3 * 15 and 5 25. Yes. So 47 into 35 answer multiply 35 and 23 21 to carry 1 6 45. Option A is correct. 1 6 45.

[00:23:50]Okay. Question number 58 here. Joseph bought a mobile phone listed at 2,800.

[00:23:58]if he got a discount of 7 and a half% on it and paid tax at rate of 10%. Ah questions regular b my regular b so percent similar question solve 28 280 and first case are discount. So discount 7 and half discount still 92.5 and paid tax at a rate of 10%. So tax pay so 100 s by 100 like this. Okay. Now zero.

[00:25:00]Okay.

[00:25:12]calculation and divided by decimal divided by 10. 2849 or 2849.

[00:25:32]Okay. Because cancel 2849 in uncarch one you will get the marks. Okay. Next.

[00:26:02]Say answer multiplied by 11.

[00:26:07]Divisibility rule of 11 either zero or multiple of 11.

[00:26:24]minus either zero or 11 So - 6 11 so 11 multiple option D answer by this method also question GK group A question group A level now question number 59 the difference between discount of 40% on changa lay two successive discount of 36 lay four on same amount a uh discount difference 36 + 4 minus 364 * 24 to 14 by 100 so 1.44 1.44 difference so find out 1.44% 44% of Zanga M% into 500 B 1.44 into 5 0 2 carry Z 0 + 2 2 carry decimal 5 into 1 + 2 7.20 7.20 20. So 7.20 in answer chan you will get the marks. Okay. Next question.

[00:28:10]Question number 60. Exact value exact questions.

[00:28:15]What percent of 7.2 kg is 18 g. Now 18 g smaller unit and larger bigger unit anoa like this into 100%.

[00:28:31]Okay, 18 g 7.2 kg and kg because ratio always unit in 100%. Now decimal.

[00:28:48]Okay.

[00:28:52]18 by 72 18 four time and 1x 0.25 0 decimal 2 * 8 0 5 * 20.

[00:29:14]So 0.25% here.

[00:29:18]Now next question.

[00:29:20]If A's income is 30% more than B regular B aspirants in all these questions. Okay.

[00:29:31]144 by 100.

[00:29:37]Okay.

[00:29:39]144 by 100.

[00:29:41]144 by 100 denominator 10 100 1,000 10,000 1.44 44 like this. No need to Okay. Now A income is 30% more than B.

[00:30:13]So by what percent voice clear voice voice because clear. Okay. Okay. Clear. Now A's income is 30% more than B.

[00:31:01]So B 100.

[00:31:07]Now B's income less than A and A always into 100% 300 by 13 options denominator 13 option A.

[00:31:29]So option A is correct or direct formula a by 100 + a into 100% direct formula 30% 30 like this 0 0 cut so zum by 13% is correct and multiply 23 * 69 23 9 29 + 1 Option A here Adik.

[00:32:01]Question number 62. In an election, there were only two candidates. Okay.

[00:32:06]The winner obtained 56% of the vote and won by 8,400. So 8,400 margin 8,400.

[00:32:19]Okay. So margin winner loser and winner in 56 loser these are 56% winner loser in 100 minus 56 that is 44% 8400 marginal difference So 12 unit value 8400 each one unit value and total number of vote p so total number of vote 100% so 700 multiply 70,000 8400 person 6 total number of votes p 100 unit value 70,000 okay 70,000 a question number 63 question number 63 a shopkeeper bought a bat for 490 and sold it loss.5 in 50 89 it will be 73 oh so 7350 by a cost price za into 100% like this.

[00:34:14]So 0 0 0 735 by 49. Now option 14.

[00:34:31]Okay. 49 Li 245 Z 53 7 uh 15% he guys 100% it is correct 15% he add okay next by selling a table for 6384 shopkeeper loses 5% how much did he purchase it cost price find out and cost price again selling price into 100 by 100 plus minus loss or profit person that's why 100 so and selling price 6384 okay 6384 638 uh 638400 0 divided by 95. So 6720 6720 I am I am back.

[00:35:53]846% 56 minus 44 Hemiapia 8,400.

[00:36:08]Okay.

[00:36:11]12 unit and 12 unit 8400 one unit again.

[00:36:18]So 100 unit next. A radio is sold at a gain of 16%.

[00:36:30]If it had been sold for 20 more, 20% would have been gained.

[00:36:36]Gain gain gain gain always 16 20 both are gain so uniffer 20 - 16 4% and 4% value 20 price always 100% so 100% 20.

[00:37:05]So option C 62 SAS 62.

[00:37:17]Okay.

[00:37:21]6500.

[00:37:24]Yes. 500 is correct. Next.

[00:37:27]By selling 45 oranges for 800 uh 80, a man loses 20%. And yeah, how many should he sell for 48 so as to gain 20% in the transaction? Uh by selling 45 oranges for 80 rupees, a man loses 20% a loss loss. Cost price find out cost price of 45 oranges.

[00:37:53]selling price into 100 45 in now 20% 20% it means 20% 100 okay so 45 oranges is in 120 is selling price for 45 and how many should he sell for 48. So x is equal to 48 like this solve. Okay.

[00:38:42]So solve uh x = 120 into 48 by 45.

[00:38:57]and 20% 20 unit is equivalent to 48 45.

[00:39:05]So one unit one unit will be by 45. Yes.

[00:39:16]And 48 unit.

[00:39:19]So 120 into 48 by 45 and each one cancel uh 9 in 40 time 3 in 15 and 16 by 5 8 time 16 Eight.

[00:39:51]45.

[00:39:54]Oh, just wait. Just wait. Concussion. How many rupeeities?

[00:40:06]Okay. Sorry. Quantity. How many?

[00:40:11]So how many 45 unit?

[00:40:22]So is equivalent to 45 is equivalent to how much? 45 by zasni.

[00:40:31]Okay. And 45 48 rupee.

[00:40:37]One unit value is 45 by 120. So 48 rupee 48 rupee unit will be 45 by 120 into 48 like this. So 45 by 120 into 48 12 in 10 time 12 in four time 5 in two time 5 in 9 time 2 in two time. So 9 two time is 18 to 18 is correct answer. Okay. 18 unitary method inva basic 67 ratio of zinc and copper in a brass piece is zinc clay zen and copper 13 is to 7 and yeah how much zinc will be there in kiza zinc 13 unit and anoa 20 into KZA 5A.

[00:41:38]So 13 five time is 65 correct answer.

[00:41:57]Smart study because already A + B whole square A square + 2 A + B square A + B whole A + 3 A bracket A + B + B means those three questions.

[00:42:33]Okay, next question.

[00:42:52]Pakma is the 35 kg 35. No 35 zinc 35 copper 35 answer question is zinc and zinc is 13 unit that's why 65 35 orange cost 35 orange costs So uh next he ratio between two numbers five.

[00:43:52]If five is subtracted from each of each number the ratio become 4 is to 5 4 by 5 by 55 9 by 11 five 20 by 25 I 5 by 6 and subtract 4x 5.

[00:44:34]Now cross multiply 5 into 525x 5 into 525 6 into 4 24x - 5 into 4 20 x number number. So x is equal to x = 5.

[00:45:08]6 x 5 multiply 30.

[00:45:12]So 25 13 uncertain you will get the marks unnecessary screening. Screening permutations.

[00:45:48]Okay.

[00:45:53]At least 100 otherwise next exam solutions at least in like now question number 70.

[00:46:07]Question number 70. In a mixture of uh mixture and allegation 60 liter milk five unit milk 5x 6 into 6 and water quantity of water and Add ratio 4 is now cross 15 to 3 4 into 10 40 4 into x like this 40 and four in two time 30 time means 27.5 option D correct answer okay let's go now this one what is the least number to be added to 7700 0 to make it a perfect square. Okay. 7 7 0 0 group of two. Now just below 77 perfect square 64. So 8 into 8 64 and next step. Eight bill 55 26 5 * 90 1666 in 363 9 167 7* 49 4 3 uh 42 64 Oh and 168 8 times 64 6 48 54 5 88 square find out 88 square 664 7704.

[00:48:53]So 744 perfect square. This is the least number. Okay. Option Aik 100% this one 44 in uncarch one you will get the marks like common problem. This one seventh tree 7th cube root of cube root of 4 12 by 125.

[00:49:54]Now 125 four time by 125 and cube root and 8 by 5 into 1 15 + option Bik Okay.

[00:50:24]Next sultan indices type question.

[00:50:41]Okay. Now this one a this one. Oh, seventh tree here.

[00:50:51]Five people were asked asked the amount of time in a week they spend doing social work in their community.

[00:51:00]They said 10, 9, 12, 19 and 15 hours respectively. mean or average time in a week. Average 10 + 9 12.

[00:51:31]So answer in answer uh you will get the marks. Okay. Next question.

[00:51:40]Mean of 30 observation was found to be sumuk and each one sum equal to sumin but later it was discovered that 86 was misread as 68.

[00:52:01]30 that's why 30 in so into and it will be how much 81 and 30 in There is a rule YouTube 18.

[00:52:47]So 18.

[00:52:50]So 606 so 60.6 in uncertain you will get the marks. Okay.

[00:53:18]Oh, main thing is 13 hours 60.6 30.

[00:53:44]Next question.

[00:53:46]75 A B start a business A invest in B and what is B share 56,000 profit in each one okay and 10 into 10 and 15 into 100 158 8 * 80 + 40 is to 6. Now concl 0 0 363 and 33 by 11.

[00:54:41]Now 30 time 30 time is and 60 five time 55 400 500 four * 44 and 56 and five time point something but the nearest value is this one.

[00:55:17]Option C. So option C.

[00:55:21]Okay. Next this one solve.

[00:55:32]No maharen 76 metaharan chanin ajay and raahul's investment is in the ratio 5 is to2 a get 3420 is profit after donating 10% of total profit to orphanage basic consultation 100 money profit 100% 90% so consult little bit simp Okay. Donation donation.

[00:56:30]So donation donate donation is to a is five unit and a get three.

[00:56:52]Get 3 420 a two unit value find out 486.

[00:57:08]So one unit value 684 and each one two unit value 16 1368 option D here correct answer 1368 left hand side right hand Next question.

[00:57:44]Running at a same constant rate. H same constant. Same constant.

[00:57:51]Same constant rate. Six identical machine can produce a total of 270 bottles per minute. So per minute per minute means per unit.

[00:58:07]So in MDH MC by work into wage is equal to M_sub_2 D2 H2 M2 by work to wage 2.

[00:58:30]So six machine into 1 minute by total work.

[00:58:38]Next part 10 such machine. So 10 such machine.

[00:58:46]Okay. How many bottle could be produced?

[00:58:52]X 10 into 4 into 270 by 6 cancel uh oh cancel four time five. So 45 four time is somria nbakad.

[00:59:16]So politics 7th 2500 children in a school had enough chocolates for 40 days. Okay. So question three methods but some children never came to school.

[00:59:49]Okay. And chocolate lasted for 50 days.

[01:00:01]1 equal to M_sub_2 D2.

[01:00:05]Okay.

[01:00:06]Total children sang into they had enough chocolate for 40 days. Now next M2 but some children never came to school.

[01:00:24]So into chocolate last for 50 days simply value of x.

[01:00:35]So 25 into 4 into 2500 uh it will be n minus 50x 50x.

[01:00:54]So 50x equal to is value of xid.

[01:01:08]So zero five.

[01:01:14]So option C is correct.

[01:01:19]Z is correct. Next.

[01:01:22]This one.

[01:01:24]A can do a work in 20 days. B can do it in 12 days. B worked it it for B worked at it for 9 days and left the job. Okay.

[01:01:39]How many days? A aloneabove remaining LCM little bit easy 20 40 16 by 23 60 by 12 B.

[01:02:05]So B efficiency finish. So left total work a efficiency 5 days are finished. So option B here correct answer. Left hand side 5670 hit two in zero.

[01:02:47]Okay. Okay.

[01:03:00]But let me practice overcome. Let me question two pipes A B can fill a system in 24 minutes 30 minutes respectively.

[01:03:10]Sistn has an outlet C also. Okay. outlet.

[01:03:21]First one in second one in 30. Third one in a vine 20 minute.

[01:03:34]Now value of x final 1x 24 + 1 by 30 1 by 20 and 1x LCM 590 120 120 le rook oh so le equal to 1x by X by 121X.

[01:04:12]So option A 34.

[01:04:19]No 34 minutes. Okay.

[01:04:36]42. Now this one A and B can do a P. So for 30 B C 24 A 30 24 20 30 24 LCM A + B 30 days B L C 24 days C L A 20 days now anglavila LCM is zasni four time five time six time total efficiency C. Uh 6 + 4 10 + 5 15 A C. So a + b + c 2 now a + b + c 7.5 and efficiency and in how many days so day find out total work by efficiency total work efficiency 7.5 decimal.

[01:05:53]Now 25 in cancel three time 25 in cancel four time 3 into 12 four time. So 4 into 4 16 days. This is correct answer.

[01:06:13]Now next this one 82 a thunder cloud is at a distance of 3.3 kilometer if the sound of thunder cloud follows the flesh after 10 second speed of sound speed of sound find out 332 m okay speed of Okay. Thundercloud.

[01:06:54]Speed equal to distance into time.

[01:06:57]That's it.

[01:07:01]Distance is 3.3 kilome and time he 10 second.

[01:07:09]Now kilome so 3.3 into 1,000 into 10.

[01:07:24]So 33,000 H sorry in speed distance by time 3.300 and 10 second kilome like this Option A. Okay.

[01:08:07]7:30.

[01:08:09]Uh 7:30.

[01:08:12]Just wait.

[01:08:22]Just wait.

[01:08:46]Yes.

[01:08:48]Question number 83.

[01:08:51]Question number 83.

[01:08:54]Now question says that uh class maths 3 to four months are sufficient basic knowledge paper 5 by 18 5 by 18 3.3 km and time kilome hour kilome hour 18 3.3 km per hour kata Yeah.

[01:09:52]3.3 km convert 3.3 km.

[01:10:09]Next. How long does a train how long means time? Find out distance by speed.

[01:10:16]Now distance running at a rate of 80 kilome per hour.

[01:10:22]Oh all the options are in second.

[01:10:28]So speed 80 kilome hour that's why 5 by 18 in multiplying like this and into 18 like this zero zero four in five time four in two * Five play five two in nine time 18. So option D here he option D is very much correct. Next this one. Okay.

[01:11:25]84 here. Timotei is traveling on his cycle and has calculated to reach his home at Daruka. Okay. If he travels at 10 kilometer uh per hour, he will reach there at 4 p.m.

[01:11:44]in hour. Oh, at what speed must he travel?

[01:12:00]Okay. Okay.

[01:12:14]distance that's why distance for case one is equal to distance for case 2 and distance speed 1 into t_1 and speed 2 into t2 distance constant first speed second speedome and tus.

[01:12:51]Okay.

[01:12:54]Interesting.

[01:12:56]So cancel five t 3 t and three multiply six minus 6 and 2t 3 tus 2t is only tal 6 hours. Now distance find out 10 kilome hour speed 15 km per hour speed first equation. So 10 into 6 60 kilometer anchu.

[01:13:46]And next at what speed must he travel to reach his home?

[01:14:08]So 6 hour 1 hour only 5 hour. So 12 kilometer per hour is correct. Option C here.

[01:14:22]Okay. Option C will be correct answer.

[01:14:26]Next.

[01:14:48]Next 85 in what time will amount to 5% perom simple interest?

[01:14:59]amount 5% rate. So time find out simple interest equal to P RT by 100. Now simple interest aap means what? Gap means zaka. So 900 is equal to 3600 equal into rate is 5 * t by 100. Now in 100 so t is equal to 5 years to 5 years in answer you will get the marks. Question number 86. Compound interest on 162 by3% perom 2 years. Now 162 by 3 48 + 2 50 by3.

[01:16:03]So 540 50 by 3 0 0 0 18 five * 9 and percent 90 and 90 again 50 by 3% confine and concord for two year. So one option C correct answer. Okay. Option C is correct.

[01:16:52]Question number 87. At what rate of compound interest will Singh become Singhi after 2 year? So compound interest become always 242 and this is nothing but only amount formula P 1 + R by 100 raised to the power n P 1 + R by Direct direct amount equal to P 1 + R by 100 T. Now amount 24200 NP exe 1 + r by 100 raised to the power two zero 2 in time 2 in 100 time 1 + r by 100² 100.

[01:18:03]So 121 by 100 = 1 + r by 100² like this.

[01:18:21]21 square root is 11 100 square root is 10 square root square 1 + r by 100 11 by 10 - 1 and r by 100 so cross multiply 11 - 10 1 0 rate of interest 10% option B is correct Answer.

[01:18:52]Okay. Option B. Adik.

[01:19:00]Next question.

[01:19:11]for exempt railways 88.

[01:19:42]like this.

[01:19:44]Length of minute hand of a clock is 12 area swept by the minute hand in 35 minute is okay. Now concept total complete angle area for theta by 360 into p<unk> r² dum da duk Dariat dar.

[01:20:31]So the meaning of this question is 87% 87. Okay. 88 solve. So 360 complete angle circle and division division division 30° division 30 division 30 30 division 30 30 30 30 zriat Hello.

[01:21:21]So 35 minutes and 35 minutes.

[01:21:35]It means theta is s.

[01:21:40]So solve theta and 360 pi r². Now p<unk> 22x 7 12 into 12 like this. Okay.

[01:22:04]Yes. So Kila 0 and 12 in 36 3 time 3 in 21 7 * 7 and 22 into 12 can answer 22 10 time is an 22 2 * 44 so and area always cm square cm Cime always cm square. Option D.

[01:22:58]more than 80 to 90% and 80% 90% score question number 89 89 9. How many silver coins? 1.75 cm in diameter and thickness to mm must be melted to form a cuboid.

[01:23:40]Number of silver coin is equal to cuboid.

[01:23:49]Silverluboid silver.

[01:23:56]So how many n into volume of silver coin silver coin silver A and A gold symbol chemistry. So silver is equal to volume of cuboid. Volume of cuboid cylindrical form that's why n into pi r²h and volume of cuboid ain a l into b into hin. Okay. Cube A. So L into B into H N into 22X into 1.75 diameter each one 1.75 by2 whole square into a height a thickness 2 mm.

[01:25:05]Now all the datas are cime.

[01:25:17]and 10 in.

[01:25:19]So 10 mm cm 2x 10 means 0.2.

[01:25:26]So 0.2 length is 5.5, breadth is 10 and height is 3.5.

[01:25:36]Calculation total n will be 5 into 5 10 3.5 7 and 2² pi by 22 1.75 into 1.75 into 0.2 2. Now 35 time two time 11 in five time 11 in two time 35 five time two in 10 five time zero zero Five zero seven 25 time five in five time and ang five. So by five 400 400 is correct answer. Okay. 400 exam complaint serious. Okay.

[01:27:11]Yeah. Today's exam complain 400 you will get the marks. Next question.

[01:27:22]A toy is in the form of a cone mounted on a hemisphere. Corn mounted on hemisphere after a very long time.

[01:27:42]Now common radius is common base radius is 7 cm.

[01:27:55]Total height of the toy. Okay. Total height of the toy.

[01:28:01]Height of the cone.

[01:28:11]Total surface area of toy.

[01:28:15]Total surface area.

[01:28:19]Curved surface area of hemi cone and curved surface area of hemisphere.

[01:28:32]Because now curved surface area of cone pen height curved surface area of hemisphere 2 pi r² pi r + 2 r pi I 22x 7 R means hemi length is length height and L fin 24 7 always 25 triplet 7 24 triplet so height plus 2 into R radius so 7 22 and 39.

[01:29:38]So 39 into 22 78 and 78 58.

[01:29:50]So 858 in answer Jan you will get the marks.

[01:29:56]Thanks.

[01:29:58]Oh 85.

[01:30:09]Anyway all these previous So now this one 91. A bucket is in the form of a frost.

[01:30:39]Hold 28 28.49 the radi of top and bottom. Okay. 28 cm and 21 cm. Okay. Height of the bucket. Find out height. Find out height. Find out formula first of volume formula volume is equal to 1x3 pih bracket capital r² + small r² + capital r into small rul 28.490 490 L cm cube.

[01:31:47]Yes.

[01:31:49]1,00 cm cube is equivalent to one lit non. And one more thing, measuring tape, cardboard, 1 m by 1 m by 1 m.

[01:32:22]continue.

[01:32:23]So 28.490 490 into 1,000 cm cube. Hello 1x3 p<unk> 22x 7 hine and uh 28² 784 anina 21 square 441 and uh 28 into 21. So 28 21 28 56 588 Okay. 5 88 588.

[01:33:09]So 588 1029 and 1029 784 3 1. Oh 1813 guys.

[01:33:24]1813 2849 22h by 21 into 1813. So multiply number 28490 divided by 1813 multiplied by 21 and divided by 22.

[01:34:07]15 means you will get the marks. Next, it is required to sit.

[01:34:21]It is required to seat anymore five men and three women in a row so that the woman occupy women occupy even places.

[01:34:32]Men, woman, men, women, men, women, men.

[01:34:39]Men.

[01:34:43]Woman number one.

[01:34:48]Woman number.

[01:34:56]So out of even places and these are the even places. Second, fourth, sixth, eighth. Okay. So, one woman.

[01:35:20]It means that out of four places three are okay and multiplication and man five factorial.

[01:35:40]So five factorial is 5 into 4 20 into 3 60 into 2 z and 4 p 3. Now 4 P3 4 into 3 into 2 24 anid on 24 and 12 into 24 12 144 into 2 288.

[01:36:08]So 288 280 here.

[01:36:12]Okay. Next question.

[01:36:15]Sitting arrangement means permutation combination. Question number 93.

[01:36:27]Reasoning passing away seems easier than yes. Ninth tree only seven questions. So fast ninth tree four post of five teachers there are 23 applicants total applicants 23 two posts are reserved for ST. So total post and so non reserved seven there are seven schedule cast among them. So how many ways can the selection be made?

[01:37:36]Oh okay. So how nsc 72 multiplied by 16 C3. That's it.

[01:37:55]unfine non SC16 and two posts that's why NCR 16 C three and total SC applicant and SIM so first SC candidate second Seat number one SC number one in seat number two SC number two in seat number two SC number three in seat number two SC number four candidate in seat number two that's why 7 C2 16 C3 so 7 C2 7 into 6 by 2 and 16 into 15 into 14 by 3 into 2 6 Twin tree time and optional 11 into 6 into 16 into 15 into 14 divided by so option C correct answer anid. Okay.

[01:39:20]Option C is correct answer. Next 94.

[01:39:25]A letter 15 m long just reach just the top of a vertical wall. I mean vertical wall and yeah if the letter makes an angle 60 with the wall or with the wall with the ground and with the wall. So hemi is 60° and later is 15 m.

[01:39:54]Angle of depression type question angle of depression always 60 and hemi 30 and if this is 30 alternate angle he 30° height of the wall height means perpendicular hypotenus means hypotenus so perpendicular Similarly, hypotenus sin theta penus is 15 sin 30 1 by 2 sin 30 is 1x 2 and 15.

[01:40:43]So 15 by 2 correct answer 15 by2 question number 95 an observer 1.5 m tall okay observer 1.5 height tall is 28 oh 5 m away from a chimney. This is a chimney.

[01:41:17]The angle of elevation the top of chimney top 45.

[01:41:28]So 28.5 28.5 and if this is 28.5 45° base height always when the angle is 45 so hemi 28.5 height of chimney so height of chimney layer in ground the trunk in total length height missing 1.5 m plus 28.5. So 28.5 for 1.5 30 m option B is correct answer.

[01:42:13]Okay. Now next next solve lea this one 96 A from the top of 9 m height uh 9 m high building angle of elevation of the top of a cable tower is 30 and the angle of depression of its foot is 60 height of the tower. Okay.

[01:42:41]Repeat fire repeat these type of questions from the top of 9 m of building. This is a building. Angle of elevation of top of the cable is tower is summon and angle of depression of its foot is hemi and direct alternate angle height of the tower height already this one 9 this one.

[01:43:37]So with the help of this triangle find outpendicular sopendicular base 10 theta. So 1060 equal to 9 by X and 1060 again uh roo<unk>3 9 by X X and root tree like this and 9 by root tree means 3 into tree root tree in tree one more three root3. So base 3 <unk>3.

[01:44:16]Now base 3<unk>3.

[01:44:20]So height perpendicular 1030 = to h by 3 <unk>3 is 1 by roo<unk>3. So root.

[01:44:42]So 9. So 3 m 9.

[01:44:57]Okay.

[01:44:59]Next 97 only.

[01:45:05]And after that stop given pie chart shows the mark scored in an examination by a student in mizau English maths essays science and if total mark obtained by the student is in which subject did the student score 135? Oh chart and pie chart 360° total mark 540 given. Now concl 135.

[01:45:46]So 135 is equivalent to x°. Now x° science 60s like that. So solve x = 360 into 135 by zi three time two time 45 time 2 into 45 90° and 90° English is correct option Bik long life the King.

[01:46:42]So English is correct answer. Experience experience.

[01:46:53]Question number 98. The line graph gives the ratio of the amount of imports by a company to the amount of exports from that company. Okay. Okay. Ratio ratio 0.

[01:47:20]If the imports of the company 2019 2019 only this one 0.35 85 85 No need to say 0.85 0.85 0.85 import export and ratio ratio import by export and ratio value is 0.8 85 can import 272.

[01:48:23]So export find out.

[01:48:26]Okay. Export.

[01:48:32]So find out export equal to 272 by 0.85.

[01:48:42]can solve 272 divided by 0.85 85 320 crores.

[01:48:52]Option B in uncarch you will get the marks five 172.

[01:49:10]So 1620 time.

[01:49:15]Next 98 99 the table shows below uh the table given below shows the total population of five different uh cities and yeah ratio of male to female given to literate population oh the literate population in city C is how much person more than male population literate population in C five zuk 7th 72%. So 72% of Kim Zuki 12 42 + 1 43 male population in city D. So male 5 unit. So 5 by total male plus female 9 into a population 720.

[01:50:10]Okay.

[01:50:13]Uh 9 and 5 over 432 into 100 more than that of city B. So city D compare.

[01:50:36]So 2x4 8% 8% is correct answer.

[01:50:50]Okay. Answer and answer please.

[01:51:14]Question number 100. The bar graph given below shows the number of shirts of five different brands A, B, C, D, and E sold during a particular month. By what person does B R and E B and brand?

[01:51:36]By what percent does brand E need to boost its sale to catch up with its nearest rival brand?

[01:51:46]Nearest rival brand.

[01:51:53]Please remember and arrival. Rival just above this number.

[01:52:37]Uh, arrival.

[01:52:53]Est arrival just above 470 So rival is BP gap is somria and 80 by I mean 470 into 100%.

[01:53:40]0 800 by 47%.

[01:53:46]option denominator 47 only option answer.

[01:53:56]Okay.

[01:53:59]Yes. Yes.

[01:54:02]By what percent does brand E need to boost? So E can boost arrival brand. Arrival brand.

[01:54:15]So difficulty 100 on a scale of 1 to 10. 1 to 10 moderate easy and a difficult few questions are there which are so I think out of 10 out of 10 5.76 fa moderate questions are good but just above moderate. Easily above easy moderate an ongoing ongoing class or other coaching institute.

[01:55:20]Nice.

[01:55:31]That type of exam 7 to 8 because banking questions PSC questions n S CGL questions 8 to Aarm G analyze me analyze but and current affairs that's why and few only reason But solve answer.

[01:56:25]So thank you so much for attending this session and request. Okay, good night to all of
