Question

After 16 years, Seema will be three times as old as she is now. Find her present age.

Answer 1

Let the present age of Seema be x years.
After 16 years:
Seema's age = x + 16

After 16 years, her age becomes thrice of her age now
∴ x + 16 = 3x
or, 16 = 3x − x [Transposing x to the R.H.S.]
or, 2x = 16
or, `(2x)/2=16/2` [Dividing both the sides by 2]
or, x = 8 years
