Ramu's father is four times as old as Ramu. After 16 years,he will be just twice his son. find their present age.

Let the present age of Ramu be x years.

thus the age of ramu's father=4x yrs.

ramu's age after 16 yrs.=x+16

ramu's father's age after 16 years=4x+16 yrs.

4x+16=2(x+16)

2x=16 => x=8

thus the present age of Ramu=8 yrs. and the age of ramu's father=32 yrs.
