Present ages of P and Q are in the ratio 4:9 respectively. If Q’s age, 12 years hence from now will be 4 times of P’s age, 4 years ago from now, then find the present age of Q.
Let the present ages of P and Q be 4x and 9x years respectively. According to the question, => (9x + 12) = 4 × (4x – 4) => 9x + 12 = 16x – 16 => 7x = 28 => x = 4 Therefore, the present age of Q = 9x = 36 years
