Question

the ages of Sonam and Kangana are in ratio 4:7, after 3 years from new ratio will be 3 :5 find the present age in explanation​

Answer 1

Step-by-step explanation:

let the age be 4x and 7x

after 3 years age will be 4x + 3 and 7 x + 3

therefore (4 x + 3)/(7 x + 3) = 3/5

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

20 X + 15 = 21 X + 9

15 - 9 = 21 x-20 x

6 = X

hence the present age of Sonam is 3×6 = 18

and the present age of Kangana is 5×6 = 30
