Question

Rahul is 15 years elder than rohan. If 5 years ago, rahul was 3 times as old as rohan, then find rahul’s present age. A. 32.5 years b. 27.5 years c. 25 years d. 24.9 years

Answer 1

Rohan's age = x

Rahul's age = 15 + x

5years ago

Rohan's age = x - 5

Rahul's age = 3(x-5)

15 + x - 5 = 3x - 15

2x = 25

x = 12.5

Rhan's age = 12.5

Rahul's age = 15 + 12.5 = 27.5 years

b) 27.5 years
