Answer:Boys=5,girls =2

Step-by-step explanation:

Let b be the no of boys and g be the no of girls

Therefore

Sam has twice as many brothers as sisters

2g=b-1

b-2g=1--------------1

Amanda has five times as many brothers as sisters

5(g-1)=b

5g-b=5----------------2

using (1) & (2) we get

g=2

b=5
