Question

the sum of age of gagan and jessica is 31.After 10 years the ratio of the ages will be 8:9.Find their present age

Answer 1

Step-by-step explanation:

Gagan + Jessica = 31

After 10 years, G : J = 8 : 9

Sum = 31 + 10 + 10 = 51 years

AQT,

8x + 9x = 51

17 x = 51

x = 51/17 = 3

Gagan = 8x = 8*3 = 24 years

Jessica = 9x = 9*3 = 27 years

PRESENT AGE

Gagan = 24-10 = 14 years

Jessica = 27-10 = 17 years
