Question
The current age of B is 40% greater than the present age
of 'V'. The age of 'V' five years from now will be the same as the age of 'B' five years ago. Determine the average age of 'V' and 'B' three years from now.Solution
ATQ, Let, the present age of 'V' be '5v' years So, the present age of 'B' = 1.4 × 5v = 7v years ATQ, 5v + 5 = 7v - 5 2v = 10 v = 5 So, the average age of 'V' and 'B', after three years from now = 5 × {(5 + 7) /2} + 3 = 33 year
