Question

Mohan's mother is twice the age of Mohan 10 years earlier Mohan was 20 years younger than her mother find their present ages

Answer 1

let the present age of Mohan be x

Then, his mother's present age = 2x

10 yrs before,

Mohan's age = x-10

his mother's age = 2x-10

A/q

(x-10) + 20 = 2x-10

x -10 +20 = 2x - 10

x + 10 = 2x -10

2x - x = 10 +10

x = 20

Mohan's present age = 20 yrs

his mother's present age = 2×20 = 40 yrs
