Question
The ratio of the present ages of P and Q is 6:5
respectively. If the age of P 12 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 6x and 5x years respectively. According to the question, => 6x + 12 = 2(5x – 4) => 6x + 12 = 10x - 8 => 4x = 20 => x = 5 Required age = 6x – 2 = 28 years
