Question

Prithvi’s age after 15 years will be 5 times his age 5 years back. What’s the present age of Prithvi? *


​

Answer 1

Assume, present age of Prithvi = x

After 15 years = (x + 15) years

5 years back, her age = (x - 5) years

A.T.Q.

5(x - 5) = x + 15

5x - 25 = x + 15

5x - x = 15 + 25

4x = 40

x = 40/4

x = 10

Present age of Prithvi = x = 10 years
