were 18 and 9 so I am 9 years older than sister

82 - 9 = ?
73
When your age is 18 years old that time your sister's age is half of your age that means 18/2 = 9 years

So difference between you and your sister's age is 18-9 = 9 years

so your sister is 9 year younger than you.

So when your age will become 82 years that day you sister's age will be 82-9 = 73years.

I hope this answer help
