Question

Sachin is younger than Rahul by 4years. If their ages are in the ratio of 7:9, how old is sachin

Answer 1

Let age of Rahul be x
So age of Sachin is x-4
Ratios = 7:9
ATQ
x-4/x = 7/9
By cross multiplying
9(x-4) = 7x
9x - 36 = 7x
9x-7x = 36
2x = 36
x = 36/2
x = 18
Age of Rahul = 18 yrs
Age of Sachin = 18-4 = 14 yrs
