Answers and Solutions for IBPS Clerk Quantitative Aptitude Study Material:
1) Answer (C)
Let the present ages of daughter and mother be d and m respectively.
7d = m
19(d-4) = m-4
=> 19d – 76 = 7d – 4
=> 12d = 72
=> d = 6 and m = 42
Mother’s age four years from now will be 42 + 4 = 46
2) Answer (D)
Let the Kavita’s present age be 2x.
Sarita’s present age is x.
Now, 8 years hence,
(2x + 8)/(x +8) = 22/13
26x + 104 = 22x + 176
x = 18
Hence, Kavita’s age = 18*2 = 36 years.
Option D is correct option.
3) Answer (D)
Let the agesof Nishi and Vinnee be x and y.
Now, as per given conditions,
(x/y) = (6/5) i.e 5x=6y
after 9 years,
(x+9)/(y+9) = 9/8 i.e 8x-9y=9
After solving we get x = 18 and y = 15.
Differences in the ages = 18-15=3
Hence, option D is correct.
4) Answer (E)
Let Nikhil’s monthly stipend be equal to S.
So, monthly spend on food and transport is 0.45S
Amount remaining is S-0.45S = 0.55S
Amount spent on books is 20% of 0.55S = 0.11S
Amount remaining is 0.55S – 0.11S = 0.44S
Amount spent on other expenses is 50% of 0.44S = 0.22S
So, amount remaining is 0.44S – 0.22S = 0.22S
0.22S = 880
Hence, S = 880/0.22 = 4000
As this is not given in the options, the correct answer is option (e)
5) Answer (A)
Let the ages of the father and son be F and F-26.
Their ages four years ago are F-4 and F-30.
The ratio of these ages is 19:6
Therefore, (F-4)/(F-30) = 19/6
Or, 6F – 24 = 19F – 570
So, 13F = 546
Or, F = 42 and the age of the son is 42-26 = 16
Hence, the required ratio is 42:16 = 21:8

6) Answer (D)
Let the number be X
So, 0.65X – 0.36X = 58
Or, 0.29X = 58 and X = 200
Hence, 23% of X equals 0.23*200 = 46
7) Answer (A)
Let us first get a relation between the work done by a man, woman and a child.
1 man can do a work in 4*2 = 8 days
1 woman can do the same work in 4*4 = 16 days
1 child can do the same work in 4*5 = 20 days
=> 1 man = 2.5 child and 1.25 woman = 0.8 child
2 men + 4 women + 10 children = 5 + 5 + 10 = 20 children
1 child takes 20 days to complete a work => 20 children will take 1 day to complete the same work
8) Answer (C)
Suppose pipe A alone takes x hours to fill the tank.
Then, pipes B and C will take x/2 and x/4 hours respectively to fill the tank.
1/x+2/x+4/x=1/5⇔7/x=1/5 ⇔x=35hrs
9) Answer (A)
Let the cost price of the article be X.
So, profit when it is sold for Rs. 625 = 625 – X
Loss made when it is sold for Rs. 435 = X – 435
As they are equal, it implies that 625 – X = X – 435
Or, 2X = 625 + 435 = 1060
Hence, X = 530
10) Answer (D)
Let the cost price be CP.
Profit = .15CP
Profit = Selling Price – CP
1.15 CP = 22,103
CP = 19,220
Now to obtain 25% profit, we have to sell them at 1.25 CP = 1.25*19220 = 24,025.
