Have to find the age of a family of 7. I'm told that the youngest child is 6, the oldest is 16 have a set of twins that are 15. The mean is 11 and the mean is 10. I added up all the numbers and got 73. Thought that if I added 4 I got 77 and then could get to the mean, but that doesn't answer the question. Help

Math 
jai,
what do you mean by the mean is 11 and the mean is 10?
