My answer is woman is 72, daughter is 36 and son is 48. The book answer says otherwise.

I think the book answer is wrong but I just wanna check

The book answer is woman is 36, daughter is 18 and son is 24.

[humble bolt]

woman's age = x
daughter's age = x/2
son's age = 2x/3

(x/2) + (2x/3) = x + 12
3x + 4x = 6x + 72
x = 72
x/2 = 36
(2/3)x = 48

yes I think the book is wrong
