Question
Present ages of P and Q are in the ratio 5:8
respectively. If Q’s age, 14 years hence from now will be 4 times of P’s age, 4 years ago from now, then find the present age of Q.Solution
Let the present ages of P and Q be 5x and 8x years respectively. According to the question, => (8x + 14) = 4 ×  (5x – 4) => 8x + 14 = 20x – 16 => 12x = 30 => x = 2.5 Therefore, the present age of Q = 8x = 20 years
