according to the question, kajal's mother is twice the age of kajal.

let the present age of kajal be x.

therefore her mother's present age = 2x

10 years ago, kajal was 20 years younger than her mother.

therefore x - 10 = 2x -10 - 20
>> x - 2x = -30 + 10
>> -x = -20
>> x = 20

hence, present age if kajal = x = 20 years

and present age of her mother = 2x = 2 × 20 = 40 years
