Question

age of A and B are in ratio 9 : 4 after 7 years the ratio of the ages will be 5:3 then find the present ages​

Answer 1

Answer:

A is 18 and B is 8.

Step-by-step explanation:

Let their ages be 9x and 4x

ATQ,

9x + 7/4x+7=5/3

or 3(9x+7)=5(4x+7)

or 27x+21=20x+34

or 27x-20x=34-21

or 7x = 14

or x = 2

Therefore, A = 9x = 9*2 = 18

        and B = 4x = 4*2 = 8
