Answer:

let the age of mita is X

and the age of rohan is 4x

so according to the question

sum of their ages are 20

so, X+4X=20

SO, 5X=20

X= 4

So mitas age is 4 and rohans age is 16

let Mita's age be x

so Rohan's age would be 4x

A.T.Q. ,

x+4x=20

5x=20

x=20/5

x=4

therefore, age of mita=4

and, age of rohan =4x

=4×4

=16
