anonymous · Answer

let daughter's present age = x years
then mother's present age = 3x years
6 years ago
daughter's age was = (x - 6) years
and
mother's age was = (3x - 6) years

ATQ (x - 6) + (3x - 6) = 36
4x - 12 = 36
4x = 36 + 12
x = 48/4
x = 12
so
daughter's present age = 12
and
mother's present age = 36
