five years ago raju was twice as old as peter.five yers later,his age will be 5 more than peters age.find their present age.

let peter be x yrs.yhen raju will be 2x.after 5 yrs,age of raju=2x+5and age of peter=x+5.now it is given that raju will be 5 times peter. so, 2x+5=5(x+5). by solving we will get the present age..

thumbs up
