Answer:

b. 6

Step-by-step explanation:

I'm not 100% sure if this is the answer but here was my thinking process:

1/4 of 24 is 6, and 6 + 3 is 9, so the brothers age is probably 9, and then 24-9 is 15, and the difference between 15 and 9 is 6. Once again I don't know if this is right or not, but either way I hope this helps!
