Solution -
Let the present age of Ram be 4x yrs
So, the present age of Shyam be 5x yrs
According to Question,
4x - 6/5x - 6 = 7/9
=> 9(4x - 6) = 7(5x - 6)
=> 36x - 54 = 35x - 42
=> 36x - 35x = - 42 + 54
=> x = 12
Present age of Ram = 4x yrs = 4(12)yrs
= 48 yrs
Present age of Shyam = 5x yrs
= 5(12) yrs
= 60 yrs
