Question

who can solve this.....

Answer 1

96 years before your sister was 2 years old. After 96 years your sister's age will be 96 + 2 = 98 years.

Answer 2

Hey friend,
When you were 4 years old, than your sister was half of your age i.e. 4 / 2 = 2 years.
So, we can know her present age by subtracting 2 years from your present age:

100 - 2 = 98 years.
Her present age is 98.

Hope this helps!!!
