Question
Present ages of P and Q are in the ratio 3:7
respectively. If Q’s age, 10 years hence from now will be 5 times of P’s age, 6 years ago from now, then find the present age of Q.Solution
Let the present ages of P and Q be 3x and 7x years respectively. According to the question, => (7x + 10) = 5 × (3x – 6) => 7x + 10 = 15x – 30 => 8x = 40 => x = 5 Therefore, the present age of Q = 7x = 35 years
