Answer:
Step-by-step explanation:
25
25 Years Old
If your sister was half of your age when you were 10, this means that your sister was 5 at the time. This also means that your sister is 5 years younger than you. If you are now 30, your sister would be 25 since she is younger by 5 years.
30 - 5 = 25
