the Rohan's father's age = 4x

After 5 years,

Rohan's age= x+5

Rohan's father's age = 4x+5

but Rohan's father's age = 3times rohan's age after 5 years of his present age

=3(x+5)= 3x+15

now, 3x+15=4x+5

15-5=4x-3x

x= 10 years

therefore, Rohan's present age= 10 years

Rohan's father's present age= 10 x 4= 40 years

now, Rohan's age 5 years ago= 10-5= 5 years

Rohan's father's age 5 years ago= 40-5= 35 years.
