Question
Novita's current age is 37.5% greater than Suzuka's,
with a difference of 15 years between their ages. Calculate the ratio of Novita's age to Suzuka's age 5 years from now.Solution
Let present age of Suzuka be '8x' years. So, present age of Novita = 8x X 1.375 = '11x' years ATQ; 11x - 8x = 15 Or, 3x = 15 So, x = 5 5 years hence from now, Age of Novita = 11x + 5 = 55 + 5 = 60 years Age of "b' = 8x + 5 = 40 + 5 = 45 years Required ratio = 60:45 = 4:3
