A woman is Q years old while her son is P years old.
The sum of their ages is equal to twice the difference of their ages.
Q + P = 2(Q - P))
Q + P = 2Q - 2P
P + 2P = 2Q - Q
3P = Q
:
The product of their ages is 675.
Q * P = 675
Replace P with 3P
3P * P = 675
3P^2 = 675
Divide by 3
P^2 = 225
P =
P = 15 yrs is the son
and obviously
3(15) = 45 yrs is woman
