SESSION 5 : RQ SERIES - MAINS FOR QUANTS | BANKING & INSURANCE

[00:00:00]Hi everyone this is welcome equation number 100.

[00:00:34]Okay.

[00:00:43]separate website app and YouTube channel 365 days like reasoning Englishf First question.

[00:01:29]The average marks scored by A B C together is X which is 10 more than the average marks scored by B CD together.

[00:01:36]The ratio of the marks by A to D. Okay.

[00:01:42]Quantity 1 2 3.

[00:01:49]Okay.

[00:01:51]Average mark by A together.

[00:01:58]A + B + C by 3L + C= 3.

[00:02:07]Okay. average which is 10 more than the average mark scored by B C D together X= B + C + D by 3 B C D average B C D by 3 = X - 10 B + C + D = 3X - 30 secondus B minus B cancelus Okay. 3xus.

[00:03:14]Okay.

[00:03:17]AL difference three part 30 and one part exact.

[00:03:42]Okay.

[00:03:47]A + B + C= 3X A + B= 3X 14 B + C = 3X B and C average B + C average B + C by 2 X - 5 B + C = what 2X - 10 B + C 2 - C 3x - C 2x - 10 3x - 40= 2x 3x - 2us 14.

[00:05:00]Is it clear? So x value 13 cal what x= 30 3 into 30 90 - 40 15 b + c 15 a score.

[00:05:29]Core D score information 1 2 3 A C and D together plus C plus D by 4 A score 40 B + C D score 10 / 4.

[00:06:12]So 40 50 100 by 4.

[00:06:16]So quantity one. Okay. Quantity the mark scored by a quantity two a score 40.

[00:06:28]Quantity 1antity 2 40. Nextity 3 x + yantity xal value 30 value 25 240 40 less than equal to. So quantity 1 is less than option Bantity 1 is less than quantity 2 is equal to quantity 3. Okay, clear.

[00:07:23]Okay, next question. Second question.

[00:07:54]Quadratic equation.

[00:08:07]Time speed. The total time taken by car to cover 240 km distance with the speed of m kilome per hour. Question total 240 km distance 24 distance which is equal to time is equal to what? Time is equal to distance by speed. Correct? Distance equal to speed into time. time distance by speed eight.

[00:09:13]So 240 / distance by speed 240.

[00:09:31]Sorry.

[00:09:40]So in the okay informational 24,000 into value 2400 and m and n are positive inteious. So valueantity oneity 24 * 4 480 4,800 Next so m into n - 240 which is equal to 6en.

[00:10:40]Okay. 4,800 24,000 24,000 4800al 28,800 m² + 20 which is equal to 6 * remaining four 800. Okay.

[00:11:05]Okay.

[00:11:07]4,800 m² + 20 4,800US 4,800 add 60 and 80 choose 4800 4800 either 60 or = - 80 16 -al 24,000. Okay.

[00:12:18]24,000 400 400. Okay.

[00:12:36]Okay.

[00:12:40]Yes.

[00:12:44]The distance covered by the car in m by 30 hours with the speed of nus 320 kome.

[00:12:53]Okay.

[00:12:56]Distance equal to what? Speed into time.

[00:12:59]speed n - 320 km/h value 400 - 320 m by 30 m value 60 so 60 by 3060 d quantity 160 okay Next quantity 2 the value of nus mantity 2us mus okay n - m value 400 60 so 340 okay so quantity 1 is less than quantity two option B is the right answer second optionity one is less thanantity Okay, next question.

[00:14:19]roots larger smaller second roots x² - 16 <unk>2x + 120. So x² - 16 x + 60= root simply - 10 and - 10 - 6. So x value x1 and x2.

[00:15:31]So equation one equation equation equation one and equation y² - 21 y + 1 4 = So 2 into 52 again 22 into 26 26 21 8 - 8 8 - 8 - 13 roots y1 and y2 + 8 and 13 equation value and larger root of equation 1.4 root of equation two. Equation two small equation wait a + balant ach.

[00:17:48]equation roots and equation roots and so roots root 18 product 10 into 8 into B. So 18 into 18 4 option C is the right answer.

[00:18:29]So in the concept in the concept then Okay. Next question.

[00:18:53]So in the question number series 1 4 7 14 27 48 and x. So in terms of y find the missing term in the series to evaluate the quantities y + 3 + 7 + 13.

[00:19:40]Okay.

[00:19:42]+ 218 4,800 difference. So difference + 4 + 6 + 8 correct 4 6 8 + 10 21 + 10 + 31. So 48 + 31 79 quantity 1 series y 15 33 69 141 Double 30 6 15 into 2 30 + 3 into 2 6 + 3 69. Super into 138 + 3 into 2 + 3 into 2 + 15us 12 6 into 2 12 12 + 3 15 y into 2 + 3= 15 y into 2 = 12 y = Time pressure 2 y into 13 y into 13 + 1 y into 13 + 1 y value 6 into 13 add 78 + 1= 79 again 79.

[00:22:33]So that quantity 1 is equal to quantity two. Option E is the right answer. Same okay option E is the right answer. Next question.

[00:22:43]Okay, last question.

[00:22:52]Simple interest received on X after 4 years is 4,000.

[00:23:00]Okay.

[00:23:06]Principal rate of interest or percentage X principle either rate of interest 4,000 simple interest concept and simple interest received X + 2,000 X + 2 X + 2,000 rupees rate of interest rate of interest same but two years 2 years 2500 interest simple interest find the compound interest received on 2x + 2000 after 2 years at 2 hour rate per percent sorry percent 2% percent difference x + 2000 years 400 years 2 4 years 4,000 years interest 2,500 simple interest 500 500 for 2 years 2 years 500 rupees 2,000 2,000 500 rupees 500 250 rate of interest 250 for princip 2,000 2,000 princip 1 rate of interest 2,000 250 rate of interest 12.5% rate of 12.5% rate of interest.5% percent 1 year 12.5% rate of interest 25 and 50% so 50% value 4,000 50% value 4,000% 8,000 rate of interest rate of interest rate 50% 4000% x value x= 8,000 2x + 2,000 new 16,000 plus 2,000. So new principal 18,000 18,000 new princip value 12.5% 2% 25% per random rate of interest 25% 94 again 25% rate of interest 4 divide 1 1 2 5 so into 1 into sorry into 2 into 1 9,000 and 1 125 so 10,125 again option C is the right answer 10,25 so total five questions Maxigch.

[00:28:44]Okay, next video. Thank you. Bye.
