Question

after 16 years, fatima will be three times as old as she is now. find her present ages

Answer 1

Let fatima age today is = x

After 16 year fatima will be = 3x

So, x + 16 = 3x

3x - x = 16

2x = 16

x = 8

Sp fatima today is 8 years old and after 16 years she will be

8 + 16 = 24 years old

Answer 2

Let the present age of Fatima = x

After 16 years, Fatima's age = x+16

After 16 years, fatima will be three times as old as she is now. So

3x = x+16

Or 3x - x = 16

Or 2x = 16

Or x = 16/2 = 8 years

Thus, Fatima's present age is 8 years.
