Question

Kareem is three times as old as his son. After ten years, the sum of their ages will be 76 years. Find their present ages. ????

Answer 1

Let Kareem son's age be x
let Kareem be 3x
after ten yrs =x+10=son
=3x +10=Kareem
sum after 10 yrs
3x +10 + x +10=76
4x +20=76
4x =76-20
4x=56
x=56/4
x=14
son's age =x=14
Kareem age=3x=3×14=42

Answer 2

let the present age of son be x.
hence,present age of kareem is 3x.
10 yrs later,
son age=x+10 & kareem age = 3x +10.
sum of their ages =
x+10+3x+10=76
4x+20=76
4x=76-20
4x=56
x=56/4
x=14
therfore,present age of son=14 yrs &kareem =3x =3*14 =42 yrs.
