Question
The ratio of the present ages of P and Q is 7:5
respectively. If the age of P 10 years hence from now will be 100% more than the age of Q 4 years ago from now, then find the age of P 2 years ago from now.Solution
Let the present ages of P and Q be 7x and 5x years respectively. According to the question, => 7x + 10 = 2 (5x – 4) => 7x + 10 = 10x - 8 => 3x = 18 => x = 6 Required age = 7x – 2 = 40 years
