Let P = 5x and Q = 7x. Two years ago Q's age was 7x - 2, and P's age after 4 years is 5x + 4. Given 7x - 2 = (5x + 4) + 2, so 2x = 8 and x = 4. Total = 12x = 48 years.
Ratio between age of P and Q is 5 : 7. If 2 years ago Q's age was 2 years more than the age of P after 4 years, then find their total age
