Hello Aspirants. Welcome to Online Quantitative Aptitude section in AffairsCloud.com. Here we are creating question sample From all topics , which are Important for upcoming IBPS exams. We have included Some questions that are repeatedly asked in exams.

**A reduction of 20% in the price of oranges enables a man to buy 5 oranges more for Rs 10. The price of an orange before reduction was**

A) 20 paise

B) 40 paise

C) 50 paise

D) 60 paise

**C) 50 paise**

Explanation:

Reduction in price = 20/100 * 10 = Rs 2

For 5 oranges, reduction in cost = 2/5 Rs or 200/5 = 40 paise

So actual cost before reduction = 40/1-0.20 = 50 paise

**In an examination a student who gets 20% of the maximum marks fails by 5 marks. Another student who scores 30% of the maximum marks gets 20 marks more than the pass marks. The necessary percentage required for passing is**

A) 32%

B) 23%

C) 22%

D) 20%

**C) 22%**

Explanation:

Let max marks = x

Who gets 20% of x, fails by 5 marks, this means passing marks = 20/100 * x + 5 = x/5 +5

Who gets 30% of x, gets 20 more marks, this means passing marks = 30/100 * x – 20 = 3x/10 – 20

So x/5 +5 = 3x/10 – 20

Solve, x = 250

Passing marks = 250/5 + 5 = 55

% = 55/250 * 100 = 22%

**A builder borrows Rs 2550 to be paid back with compound interest at the rate of 4% per annum by the end of 2 years in two equal yearly installments. How much will each installment be?**

A) Rs 1352

B) Rs 1377

C) Rs 1275

D) Rs 1283

**A) Rs 1352**

Explanation:

Formula for installment in CI for 2 yrs is A = I/[1+r/100] + I/[1+r/100]^{2}

So, 2550 = I/[1+4/100] + I/[1+4/100]^{2}

Solve, I = 1352

**A pipe of diameter ‘d’ can drain a certain water tank in 40 minutes. The time taken by the pipe of diameter ‘2d’ for doing the same job is**

A) 5 mins

B) 10 mins

C) 20 mins

D) 25 mins

**B) 10 mins**

Explanation:

Time is inversely proportional to the square of diameter. So,

t1/t2 = (d2)^2/(d1)^2

40/t2 = (2d)^2/(d)^2

Solve, t2 = 10 mins

**A contactor undertakes to make a road in 40 days and employs 25 men. After 24 days, he finds that only one-third of the road is made. How many extra men should he employ so that he is able to complete the work 4 days earlier?**

A) 100

B) 60

C) 75

D) 55

**C) 75**

Explanation:

4 days earlier the work is to be completed, this means in (40-4) = 36 days

After 24 days, the meaning work is to be completed in (36-24) = 12 days

Remaining work = 1 – 1/3 = 2/3

Let x extra men are to be employed. So,

25 * 24 * 2/3 = (x+25) * 12 * 1/3

Solve, x = 75

**A sum of Rs 400 amounts to Rs 480 in 4 years. What will it amount to if the rate of interest is increased by 2%?**

A) Rs 484

B) Rs 560

C) Rs 512

D) Rs 600

**C) Rs 512**

Explanation:

Increase in rate = 400*4*2/100 = 32

So increase in amount = 480+32 = 512**A retailer buys 40 pens at the marked price of 36 pens. If he sells these pens giving a discount of 1%, what is the profit percent?**

A. 9%

B. 10%

C. 11%

D. 12%

**B. 10%**

Explanation:

Let MP of 1 pen = Re 1

CP of 40 pens = MP of 36 pens = Rs 36

MP of 40 pens = Rs 40

So after discount of 1%, SP of 40 pens = 99/100 * 40 = Rs 39.6

So profit% = (39.6 – 36) / 36 * 100 = 10%**A can cultivate 2/5th of the land in 6 days and B can cultivate 1/3rd of the same land in 10 days. Working together A and B can cultivate 4/5th of the land in**

A) 4 days

B) 5 days

C) 8 days

D) 10 days

**C) 8 days**

Explanation:

A can cultivate 2/5th of the land in 6 days, so whole land in 5/2 * 6 = 15 days.

B can cultivate 1/3th of the land in 10 days, so whole land in 3/1 * 10 = 30 days.

A and B together can complete whole land in 15*30/(15+30) = 10 days.

So 4/5th land in 4/5 * 10 = 8 days

**A does half as much work as B in one sixth of the time. If together they take 10 days to complete a work, how many days shall B take to do it alone?**

A) 70

B) 30

C) 40

D) 50

**C) 40**

Explanation:

Let B do whole work in ‘x’ days.

A does ½ work in x/6 days, so whole work in 2x/6 = x/3 days

Together they take 10 days, so x * x/3 / (x+x/3) = 10

Solve, x = 40 days**A and B can do a piece of work in 10 days and 17 days respectively. They start the work on alternate days with A starting the work. In how many days the work will be completed?**

A. 12 8/17 days

B. 12 8/15 days

C. 12 days

D. 13 days

**A. 12 8/17 days**

Explanation:

2 day’s work of A + B = 1/10 + 1/17 = 27/170

Multiply by 6 both sides

12 day’s work of A + B = 162/170

Remaining work = 1 – 162/170 = 8/170 = 4/85

Now on 13th day A’s turn, he does 1/10 work in 1 day, so 4/85 work in 8/17 day.

Total days 12 8/17
