SSC CGL Model Paper 12

Question : 10 of 100

Marks: +1, -0

The ratio of present ages of P and Q is 5 : 8. Three years later their ages will be in ratio 8 : 11 . What is the present age (in years) of Q?

Solution:

Let the present age of P and Q be 5x and 8x, respectively.
According to the question,

{5x+3}/{8x+3}=8/11

⇒ 55x + 33 = 64x + 24

⇒ 9x = 9⇒x = 1

Hence, Q’s present age = 8 × 1 = 8 years
