Question
At present Raveena age is 3(1/2) Diksha’s age and half
of Mitesh’s age. After 6 years Raveena will be 2 times Diksha’s age. What is Raveena’s present age?Solution
Diksha’s present age = x Raveena’s present age = 7x/2 Mitesh’s present age = 7x After 6 years: Raveena’s age = 2*Diksha’s age 7x/2+6 = 2(x+6) =>3x/2 = 12-6 => x=2*6/3 = 4 So, Raveena’s present age = 7x/2 = 7*4/2 = 14 years
