Question
The ratio of the present ages of P and Q is 8:7
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 5 years ago from now.Solution
Let the present ages of P and Q be 8x and 7x years respectively. According to the question, => 8x + 10 = 2(7x – 4) => 8x + 10 = 14x - 8 => 6x = 18 => x = 3 Required age = 8x – 5 = 19 years
