Quantitative Aptitude Questions and Answers for Bank PO and Clerk Exams like SBI PO, IBPS PO, IBPS Clerk, SBI Clerk, 2020

Directions: Read the following questions carefully and choose the right answer.
1
Tony, Monu and James completed a work together in 36 days and received a total payment of Rs. 54000. Tony took half of the total money, Monu took one third and James took remaining. In how many days, Tony and James would have finished the work if Monu was not working?
» Explain it
B
Tony, Monu and James completed a work together in 36 days.

In one day, together they will finish 1/36 of work.

Out of Rs. 54000, Tony took half of the total money, Monu took one third and James took remaining.

The shares of Tony, Monu and James are in ratio

1  :  1  :  ( 1 –  1  –  1 )   i.e.,  3 : 2 : 1.
2 3 2 3

We know that efficiencies are in the same ratio as the share received in total amount.

Let us suppose that work done by Tony, Monu and James in one day is 3T, 2T and T, respectively.
⇒ 3T + 2T + T =  1
36

⇒ 6T =  1
36

⇒ T =  1
216

Work done by Tony in one day = 3T =  3  =  1
216 72

Work done by James in one day = T =  1
216

Let us suppose that when Tony and James work together, they take N days to finish the work.
⇒   N  +  N  = 1
72 216
 
⇒ 4N = 1 ⇒ N = 54
216

∴  When Tony and James work together, they take 54 days to finish the work.

Hence, option B is correct.

A shopkeeper purchased 15 kg of variety A rice at Rs. X per kg and 10 kg of variety B rice at Rs. (X + 5) per kg. The shopkeeper sold the whole quantity of variety A rice at 10% profit and that of variety B rice at 20% profit. The total selling price of variety A rice was Rs. 30 more than that of variety B rice. Had the two varieties been mixed and sold at an overall profit of 20%, what would have been the selling price (per kg)?
» Explain it
A
  Rice A   Rice B  
Cost price 15 × x   10 × (x + 5)  
  ↓ 10% profit     ↓ 20% profit  
Selling price 110% of 15x   120% of (10x + 5)  
         
  = 16.5x   = 12x + 60  

Now, 16.5x = 12x + 60 + 30

or, 4.5x = 90

∴   x =  90  = Rs. 20 kg
4.5

Now, new selling price of mixture

=  [15 × 20 + 10 (20 + 5)]  120  = Rs. 660
100

∴   SP per kg =  660  = Rs. 26.4 per kg
25

Hence, option A is correct.

3
The ratio between the length of Cuboid and the length of Rectangle is 3 : 2 and the ratio between the breadth of Cuboid and the breadth of Rectangle is 2 : 1. If the area of the Rectangle is 140 cm2 and the height of the cuboid is 10 cm. find the volume of the cuboid.
» Explain it
B
Length of the rectangle = 2x, length of the cuboid = 3x, Breadth of Rectangle = y, breadth of cuboid = 2y
 
Area of Rectangle = l × b
 
140 = 2x × y 
 
xy = 70
 
Volume of cuboid = l × b × h
 
= 3x × 2y × 10 = 60 xy
 
= 60 × 70 = 4200 cm3
 
Hence, option B is correct.
 
4
A box contains 4 tennis ball, 6 season and 8 dues balls. 3 balls are randomly drawn from the box. What is the probability that the balls are different?
» Explain it
A
Probability =  Favorable outcomes
Total outcomes

Let us assume that all balls are unique.

There are a total of 18 balls.

Total ways = 3 balls can be chosen in 18C3 ways

=   18!  =  18 × 17 × 16  = 816  
3! × 15! 3 × 2 × 1

Favorable ways = 1 tennis ball, 1 season ball, and 1 dues Ball = 4 × 6 × 8 = 192

Probability =  192  =  4
816 17

Hence correct option is (A)

5
The length of a circular track is 800 m. Virat and Amresh started from the same point on the track and ran in opposite directions. Virat took 12 minutes to cover one kilometer while Amresh took only 9 minutes to cover the same distance. They kept running for 90 minutes. How many times did they cross each other?

A
10
» Explain it
C
The time taken to cover one kilometer for Vira tand Amresh is in the ratio 4 : 3

Their speeds are in the ratio 3 : 4.

Virat covers 3/7th of the track and Amresh covers 4/7th from one crossing to the next i.e.

Virat covers  3  × 800 m from one crossing to the next.
7

In 90 min, Virat covers  90  × (1000) = 7500 m.
12

The number of crossings
  7500 ×  7      
=  3  =  175  = 21.87
800 8

So, they will meet 21 times.
Hence correct option is (C).
