You can put this solution on YOUR website! there are 7 children with 1 set of twins. The youngest is 6 and the oldest is 16. the mean is 11, the median is 10 and the mode is 15. What are their ages?
---------
Ages from youngest to oldest: 6........10..........16
1st: 6
2nd: x
3rd: y
4th: 10
5th: 15
6th: 15
7th: 16
----
Equation:
Mean = (6+x+y+10+15+15+16)/7 = 11
-----
x+y + 52 = 77
----
x+y = 25
-----
Comment: x+y cannot be 25 if 10 is the median.
