Question
Rishi's current age is 56.25% greater than Dimple's
current age. In four years, Dimple will be 20 years old. Selina is 5 years younger than Rishi, while Anmol is 5 years older than Dimple. Determine the average age of Selina and Anmol.Solution
Age of Dimple, 4 years hence from now = 20 years So, the present age of Dimple = 20 - 4 = 16 years So, the present age of Rishi = 16 X (25/16) = 25 years The present age of Selina = 25 - 5 = 20 years Or, the present age of Anmol = 16 + 5 = 21 years Therefore, required average age = (20 + 21) /2 = 20.5 years
