Answer 2

Step-by-step explanation:

let ranjan age be 5x

let pratigya age be 6x

after 12 years

ranjan age = 5x + 12

pratigya age = 6x + 12

let

5x+12/6x+12 = 9/10

cross multiply

10(5x+12) = 9(6x+12)

50x + 120 = 54x + 108

50x - 54 x =120 - 108

4x = 12

x = 4/12

x = 3

present age are

ranjan = 9×3 =18 year

pratihka = 10×3=30 year
