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. ============================= Cheers, Stan H.
