My brother is 5 years older than me. My sister is 3 years younger than me. How old will my sister be when my brother is 29?

The answer is 21

Let us Assume that The Present Age of your Brother is 29

Given : Your Brother is 5 years Older than You

⇒ The Present Age of You is 29 - 5 = 24

Given : Your Sister is 3 years younger than You

⇒ The Present Age of your Sister is 24 - 3 = 21

⇒ Your Sister will be 21 years Old when your Brother is 29
