Rahul is 3 times as old as Seema. Laxmi was twice as old as Rahul four years ago. In four year's time, Rahul will be 31. What are the present ages of Seema and Laxmi?

Explanation

According to the question – "After the next four years, Rahul will be 31 years old." ∴ Rahul’s present age = 31 – 4 = 27 years ∴ Seema’s present age = 27 ÷ 3 = 9 years "Four years ago, Lakshmi’s age was twice Rahul’s age." Rahul’s age four years ago = 27 – 4 = 23 years Lakshmi’s age four years ago = 2 × (Rahul’s age four years ago) = 2 × 23 = 46 years Therefore, Lakshmi’s present age = 46 + 4 = 50 years.
