Question

the ratio between the present ages of P and Q is 3:4 respectively. if Q present age is 20 years, what will be the ratio of the ages after 5 years?

Answer 1

Let the present ages of P and Q be 3x and 4x

given, present age of Q = 20 years

4x = 20
X = 5

Present age of P = 3 × 5 = 15 years

Age of Q after 5 years = 20 + 5 = 25

Age of P after 5 years = 15 + 5 = 20

Ratio = P : Q
= 20 : 25
= 4 : 5

Hope it helps
