Question

two year ago, Dileep was 3 time as old as his son and 2 years hence twice his age will be equal to five time as old as his son find their present age?

Answer 1

let there present age =dileep _x, his son y
two years ago dileep =x-2,son=y-2
according to question
x-2=3(x-y)
x-2=3x-3y
-2x+3y=2__eq1
after 2 year
dileep age = x+2 son age y+2
2(x+2)=5 (y+2)
2x+4=5y+10
2x-5y=6__eq. 2
by solving eq1 and eq2
-2x+3y=2
2x-5y=6////(-2x and 2 x will cancel)
