10. Aman's age is three times his son's age. Ten years ago he was fivetimes his son's age. Find their present ages.HINT is downHint: The age of Aman's son in5(Z-10), 32-10

Answer»

let aman' s SON age = x

aman's age = 3x

ten years ago, he was 5 TIMES the age of his son.

therefore, 3x - 10 = 5 (x-10)

3x-10 =5x - 50

2x = 40

x = 20

aman' s son is 20 YRS old

aman is 3x = 3 × 20 = 60 yrs old.
