Question
The current ages of P and Q are (x + 5) years and (x –
3) years respectively. If the ratio of the present age of P to the age of Q 3 years hence is 6:5, what was the age of P 4 years ago?Solution
ATQ,
(x + 5)/(x – 3 + 3) = 6/5 (x + 5)/x = 6/5 5(x + 5) = 6x 5x + 25 = 6x x = 25 So, the present age of P = 25 + 5 = 30 years Therefore, age of P 4 years ago = 30 – 4 = 26 years
