1. Boys are so way better than girls.

2. I do have the same solution like Jorge Pardo wrote here. Just a simple math. đŸ™‚

6G +4B = 2200 pieces/4 hrs
2G + 5B = 2200 pieces per 8 hrs
B=25 pieces/hr
G=75 pieces/hr

3. I do not see if is a match among boys Vs girls!

4. Girls are three times better than the boys, putting in 75 pieces per hour versus 25 forthe boys.

5. Girls place 75 pieces/hr each and boys place 25 pieces/hr each.

6. 6G +4B = 2200 pieces/4 hrs
2G + 5B = 2200 pieces per 8 hrs
B=25 pieces/hr
G=75 pieces/hr
