Q 4 - Sabita and Ranjita are working for an MNC at the Petronas towers and to reach different floors of the same office, they use the elevators. Sabita gets on the lift at the 11th floor of a building and rides up at the rate of 57 floors per minute. At the same time, Ranjita gets on an elevator at the 51st floor of the same building and rides down by 63 floors in every minute. The question is if these employees will continue to move at such rates, then at which floor will their paths cross

Options :

A - 15

B - 36

C - 17

D - 30

Answer : D

Explanation

Let path crossed after x minutes

11x + 57x = 51-63x

x = 1/3

Floor covered by Sabita in 1/3 min = 1/3 × 57=19

So path crossed = 11 + 19 = 30

Q 5 - Sureshs father on his birthday told Suresh that he was of his present age when Suresh was born. If Sureshs father is 36 now, then how old was Suresh five years ago?

Options :

A - 15

B - 13

C - 17

D - 30

Answer : B

Explanation

Let Sureshs fathers age be x and Sureshs age be y.

Then, x y = y or x = 2y

Now, x = 36. So, 2y = 36 or y = 18.

Therefore Sureshs present age = 18 years. So, Sureshs age 5 years ago = 13 years.

Q 6 - 16 men and 20 boys can do a piece of work in 30 days. In how many days, 15 men and 15 boys will take to finish the work?

1 man = 5/4 boys

15 men = 75/4 boys

Total no of boys = 75/4 + 15 = 135/4

20 boys = 30 days

135/4 boys = 30 × 20 × 4 /135 = 17 7/9 days
