Question No 1

The ages of two persons differ by 16 years. 6 years ago, the elder one was 3 times as old as the younger one. What are their present ages of the elder person?

Select the correct answer

10 20 30 40

Solution!
Let's take the present age of the elder person = x

and the present age of the younger person = x - 16

(x - 6) = 3 (x-16-6)
x - 6 = 3x - 66
2x = 60
x = 60/2 = 30.

Question No 4

3 years ago, the average age of C and D was 18 years. With E joining them, the average becomes 22 years. How old is E now?

Select the correct answer

24 27 28 30

Solution!
Given that
[(C-3)+(D-3)]/2 = 18
C-3+D-3 = 36
C+D = 42 ...(1)

and also given that
(C+D+E)/3 = 22
C+D+E = 66

Put value of C+D from equation(1)
42+E = 66
E = 66-42
E = 24

Hence E is 24 years old now..

Question No 5

A train travelling at he speed of 72km/h can cross a platform in 17 seconds. If length of the train is 180 meters, what is the length of the platform?

Select the correct answer

Length of the train = L1 = 180m
Length of the platform = L2 = ?

t = (L1+L2)/v
By putting values
17 = (180+L2)/20
340-180 = L2
L2 = 160m

Hence length of the platform is 160m..
