→ Question : Sachin shorter than Rahul by 4 years,if his age ratio respectively 7:9 What is  age of Rachin.​

→ Answer : Age of Sachin = 18

→ Step-by-step explanation :

Let the age of Sachin be 'x'

and age of Rahul be 'y'

Given , Sachin shorter than Rahul by 4 years

So, y = x - 4...(1)

Ratio given is 7:9

=> 7 x = 9 y

sub. eq(1) in this eq. we get,

7 x = 9 ( x - 4 )

=> 7 x = 9 x - 36

=> 2 x = 36

=> x = 18

So the age of Sachin is 18 years.

and Rahul's age is 14 years.
