Math brain teasers require computations to solve.
There are six players on a coed volleyball team. After an exhausting game, each girl drinks 5 cups of water. Each boy drinks 7 cups of water. The coach drinks 9 cups.
A total of 43 cups of water is consumed by everyone. How many boys and how many girls are there on the team?
4 girls and 2 boys

|If there are six players on the team, how do you get 5 girls and 2 boys??|

|What was the coach's problem that he/she needed so much water, while it was the players doing all of the work?|

|This was too easy... after I took out the coaches water, I knew there were only two boys because that was the only way it could have ended in four... I could have solved this when i was a little kid...|

|Way too easy. |
The water the coach drinks is pointless to the teaser. The 34 remaining are 2 less than the average of 6, so there must be two more girls than boys.

|I love your logic Java. This is the way all of us should think about problem solving! Good teaser - better explanation!|
