Let us take Ravi's age as 'x' , Prakash's age as 'y' and Kumar's age as 'z'.

It is given that,     

x = 2y and ----------------> 1

x = 3z        ----------------> 2

Given : y = 24

So, substituting the value of y in 1 we get

x  = 48

Substituting the value of x in 2 we get

3z = 48

  z = 48/3

  z = 16

So, Kumar's  age is 16 and after 4 years Kumar's age would be 20 (16 + 4)

Hence the correct option is 2).20
