Question

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

Answer 1

In this question first we took the ratio present age of P and Q = 3:4

P & Q age = 20 years

So P's age / Q's age = 3/4

P's age / 20 = 3/4

P's age = 3/4 *20 = 15

So after 5 years ratio will be

P's age + 5 / Q's age +5 = 15+5/20+5 = 20/25 =4/5 = 4:5

So the ratio of the ages after 5 years will be 4:5
