Answer:

If I'm correct she will be 21

Step-by-step explanation:

Because first when your brother is 29 (-5 because your younger than him by 5 years) you will be 24 and then 24 - 3 (because your sister is younger than you by 3 years) = 21 years old. So, your sister will be 21 when your older brother is 29.
