Question
The present age of V is 90% more than that of W, and the
ratio of W’s age to Y’s age is 2:5. If the oldest person is 110 years old, find W’s age 9 years earlier.Solution
ATQ, The ratio of the age of V to W = 190:100 = 19:10 Let the present age of V = 19x Present age of W = 10x Present age of Y = 10x × 5/2 = 25x Y is the eldest, so: 25x = 110 x = 110/25 x = 4.4 Age of W = 10×4.4 = 44 Therefore, W’s age 9 years earlier = 44 – 9 = 35 years
