Question
10 years from now, the combined ages of P and Q will be 84
years. 6 years ago, the ratio of their total age to R’s age was 5:3. What is the present age of R?Solution
ATQ,
Let present ages of P, Q, and R be ‘x’, ‘y’, and ‘z’ years respectively.
So, x + 10 + y + 10 = 84
=> x + y = 64
Sum of ages of P and Q 6 years ago = 64 – 6 × 2 = 52 years
Age of R 6 years ago = 52 / 5 × 3 = 31.2 years
Present age of R = 31.2 + 6 = 37.2 years
