Question
The total age of A, B and C six years hence will be 89
years. Find the age of C five years hence, if the present age of A and B is 33 years and 24 years respectively.Solution
Sum of present age of A, B and C = 89 – (6 × 3) = 71 years Present age of C = 71 – (33 + 24) = 14 years 5 years hence, age of C = 14 + 5 = 19 years
