Apex Bank Maths Expected 2026 Paper 20| Important Questions | Tamal Sir LIVEAdded:
Hello. Good afternoon.
Good afternoon everybody.
AEX Bank. Yes. Good afternoon.
Finally, Nikki. Last exam expected paper number right behind AEX bank. Okay. So yeah, sixdigit number 11. So Mus Nel relation between M and Nel and N.
Okay.
Just a minute. So answer.
Yeah. Yeah.
Yeah. Say key and key number n 8 3 m 92.
So 11 divisible multiple right 11.
So 11 divisible alternate sum right. So n + 3 plus this one 9 12 + n minus 8 + m + 2 10. So 10 + m should be divisible minus square should be divisible by should be divisible by should be divisible by q 11 or else equal to z right 10 + m should be equal to 0 or else divisible by 11. So 12 + n = m.
So 2 is equal to m minus n that is option number b. B for bakadistic is the right answer. B for bakad district is the right answer.
Next question. Next question.
Answer right.
Yeah. The correct answer.
Yeah.
Right. Rahul answer 3780 B for BA. Okay.
Say the percentage profit earned by selling an article for 3471 is equal to the percentage loss incurred by selling the same article for 2557 profit.
Right? This is our selling price.
Percent sorry is equal to the percentage loss incurred by selling the same article for so profit equal to loss profit SP minus of CP loss CP minus of SP right so the selling price 3 471 minus of CP is equal to CP minus of selling price 2 57 correct CPI 2 7 2 7 7 + 1 is 8 5 7 2 14 carry 1 5 5 10 carry 1 4 right divided by 2 will be equal to CP 56 6 right 6 3 0 2 4 will be your CP 3024 will be your CP 3024 answer what price should the article be sold in order to make a profit of 25% 25% ACP 3 0 2 4% by 100 125 by 100. Right. So 47 28 45 46 24 76 into 5G digit 0 option B for B side that is 3780 3780 will be your right answer right 378 80 will be your right answer. 8780 will be the right answer. A right answer.

Yeah.
I'm loy.
Okay. Okay.
Right. Raj let's check answer check the lease price of a washing machine is 870 it is sold to a retailer after two successive discount of 959% and 50% wants to warrant a profit of Iman on his cost price after allowing a discount of Iman so what to the customer what price should he list the washing machine acha so a two question to follow calculate Washing machine washing washing machine.
Correct. So washing machine after two successive discounts.
0 2 discount discount 9% 91 50% means 1 by 2 a2 a2 discount factory This is the price of the retailer.
This is the cost price of the retailer.
Am I correct or am I correct?
Huh? So this is the this is the cost price of the retailer. This is the cost price of the retailer. It retailer wants to earn a profit of 25%. retailer% after allowing a discount.
Allowing a discount of market discount market 48. So 100us 48 is 52 52 by 100. Correct? This is the equation that is coming up right. This is the equation.
cost.
Cost This is the cost price of the retailer.
This is the cost price of the retailer.
This is the cost price of the of retailer.
Cost price of retailer.
48% that means 52% 100 solve. So 82 8 7 2 into 91 into 1 by 2 into market price into 2 4 26 26 / 50 50 [clears throat] right. So 13 791 correct. So 82 A2 8 8 1 8 8 8 8 8 8 9 72 say 109 into 35 into 25= market 552ig A for a right Answer right correct answer. So A4 option number A will be the right answer.
Okay.
Okay. But digital sum is not that accurate sometimes.
So I would really say digit multiples.
Okay.
Moving on to the next question. So this is our next question. Next question.
Yeah. Next question.
Everyone is getting the point.
Yeah.
Answer.
Yeah. Yeah.
So triangle same base of 24 cm. The ratio of their height is iman and the sum of their areas. See some of the areas.
Find the height of the larger triangle.
Find the height of the larger triangle.
It will be multiple of seven.
7 m 2094.
What is the height of the larger triangle? So larger question hardly 10 seconds.
Sum of the areas. Sum of the areas is 1728.
1728 question 1728 12 by 1728 larger to 7 into 12 is 84. Answer 84.
However, we say sum of the area. So area of a triangle key area of a triangle is half into base into height. Area of a triangle is half of half into base into height.
So half into base half into base 24 25.
So 24/ into 24 into 7 x is equal to 1728.
12 1x2 into base into height plus 1x2 into base into height will be equal to 172 5x + 7 X is equal to 17 28 correct. So 12 this times is 24 sorry 24 12 okay divide. So 12 into this is 12 x is = 728.
height of the larger triangle. Height height of the larger triangle will be how much? 84 12 into 7 is 84. So this smaller triangle.
Good afternoon. Good afternoon.
smaller height of the smaller triangle correct. So 12 into that is 16. Very good.
Good.
724 will be the right answer. Okay. Yeah.
Moving on to the next question.
Ed question.
Option number C sayanita answer answer C.
is inversely as y - 1.
x varies inversely as y - 1.
X varies inversely as Yus 1 inver is = 6 when Y = 3 So 3 27 is equal to 6. X value six. So this is value of K value.
Find X when Y is 8. When Y is 8. So xus 1 6 into 26 x value y is 512 512 51 x= this is 6 6 36 car 3 156 by 511 option number C. C4 will be the right answer.
C4 will be the right answer.
Right.
Okay.
It's not very easy or common.
questions are not that common. But however, these type of questions might come.
Yeah. So, moving on to the next question. So, next question is this. I want everybody to solve this question.
57.1 So 57.1 Second year CBSC class 12 CBSC okay yeah average marks of 30 students in a mathematics test were found average marks of 30 students 55.
However, it was later discovered that a mark of 72 was mistakenly recorded as 272.
Another 64 was mistaken as 46.
646 average. What is the actual average?
Because above 95 will be a total mark. 30 into 55 total marks it was discovered a mark of 72 was 27. So plus 727 next 46 30 students because 30 was 30 was the number of students divide 307.1 5315 165 5 plus 130 136US 3 4 5 6 7 right divided by 30 to D4ic yes D4istic will be the right answer right D4ic will be the right answer so D4 dangistic 57 7.1 will be the right answer. Okay. Yeah.
Right. Lux. Good. Comments. Very good.
Next.
answer.
Okay.
Yeah. So key Rahul earns an interest of rupees 296 for third year and 1400 as interest for the second year on the same sum. Find the rate of interest.
Rate of interest compounded compounded 14. This is for second year and third.
Third 29.
So gap.
So this is 6 9 15 96 divided 1400 into 100.
So 14 14 1's are 14 19 14 1 is 14 56 14 46 so 1 1 4% will be the right answer 1 4% will be the right answer right good l very good good answer very good Bangladesh comments uh 1596 yeah B will be the right answer. Sorry for the right answer.
Okay. Yeah. Moving on to the next question. Question.
Good.
Okay.
16.
Yeah. Yes. Good. Very good.
Yeah. to solve.
There is a E.
So to solve if 3 * the mother's present age is 36 if 3 * the mother's present age 3 * the mother present age is 36 more than the five times of his daughter sentence equation equation Question and 3 * the daughter's age 3 * the daughter's age is equal to 4 year less 4 year less than the mother's age and the mother's age correct now what is the mother's age what is the difference between the present age of mother and daughter correct This is equation one. This is equation one. And this is equation two. So equation two.
M= 3D + 4. M = 3D + 4. D stands for daughter. M stands for mother. Right? D stands for D stands for daughter. M stands for mother.
So 3 * of 3D + 4 = 36 + 5 D 9 D + 12 = 36 + 5 D 4 D is equal to 24. So D is equal to 6. Daughter boy of daughter= 6 18 + 4 that is 22. Mother boy 22. Mother boy 22.
daughter present age or difference present difference 22 - 6 is 16 option number C will be the right answer uh C will be the right answer Right.
Yeah. Moving on to the next question.
Yeah. Next question to solve.
Yeah. Solve.
Option A.
Okay.
Foreign speech. Foreign speech. Foreign speech.
20% answer.
Yeah.
Highest discount code. Highest discount to highest discount to the customer of customer number. So customer discount is beneficiary but correct correct option single discount singleount very good two successive discount two successive discount of 10 each successive discount formula.
Successive successive discount formula successive discount a + b minus a divided 100. Okay.
So 10% each question. So 10 + 10 - 10 into 10 divided by 100. So it comes up to 19%. It comes up to 19% 19% discount option option because two successive discounts of 8 and 12. So 8 + 12 - 8 into 12 / 100. So B base B minus 20US 0.96 0.96 4 0 19.04 19.04 discount. So because 20% is always very high as compared to 19.04 04 10 and 11. So 10 + 11 - 10 into 11 / 100. So it comes up to how much? 21 - 110 divided by 100. So it comes up to 21 minus 1.1. So 21 - 1.1 19.9 19 19.9 So anyhow we are getting that key A will be the right answer because A is discount single discount of 19 20% is always very good as compared to the other discounts right other discounts so highest number of discount scheme number one Team number one highest percentage of discount DSA say everyone is clear. So answer DS good.
Hello. So moving on to the next question. Question solve for question to solve.
Answer 5 Damon Lakshitto Raj to me this. Okay.
Moving on to the solution.
A 50 lit of mixture of milk and water contains 12% of water.
50% L of mixture of milk and water.
Okay.
12% correct. So this comes up to calculate this is 4 22 2 4 3 correct 50 L 12% so 12% % of 50 12% of 50 12%. So 12% Water.
Correct.
44 L.
44% 12%. So 12% of 50 is 6.
How much water should be added in order to make the water 20% in the new mixture?
6 + x / 50 + x is equal to 20%. 20% means 1 by 5 6 because six water is added only water added water.
Okay. So 6 + x or 50 x 5 + 5x is equal to 50 50 + x right. So this is 4x is equal to 20 x = 5. So 5 liter option number D 5 liter of water must be added. So D for dorangistic will be the right answer. Correct. D for durangistic will be the right answer.
Yeah. Moving on to the next question.

Yeah, I do.
Sorry. Sorry. Sorry.
Yeah, I do.
Yeah.
Uh lux 59 - 50 is equal to 9. Okay.
Okay.
A for America.
Yeah.
Find the range.
Maxus minimum value that is the range.
Sorry.
So that is the range maximum range maximum value maximum value minus minimum value minus minimum value right.
So maximum value 59 or minimum value is 50. So that is 59 minus 50 that is option number a a for okay so a for a for a is the right answer. Okay a for a is the right answer. So moving on to the next question. So this is our next this is our next question. To solve 163.33.
Okay. Okay.
A sum of rupees 360 amounts to 490 in 10 years. 10 years or 3600 amount 4,900.
Find the amount received after 5 years when rupees 1,400 is invested on the same rate of compound interest.
Same rate of compound interest 3600 4900 say in 10 years.
in 10 years.
Find the find the find and the amount received in 10 years and the amount received find and the amount received after 5 years when rupees find the amount received. Find the amount received after 5 years when rupes 1,400 has invested same rate of compound interest. Okay.
5 years.
5 years 1400 2* 9 5 * 10 years maximum 26 400 1400 1400 98 6. So it will be always coming in point that is option number C 16 33.3 will right answer 1633.3 right answer 3600 4900 years 5 years at the same rate of interest years 10 years.
Okay.
That is 6 1uh 1633.33 say homework.
com.
Okay.
So, okay with a new session of the math practice for ax bank. Till then I want everybody to study hard and be in a disciplined way. Take say. Yeah. Bye-bye. Thank you everybody.
