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?
\n" ); document.write( "---------
\n" ); document.write( "Ages from youngest to oldest: 6........10..........16
\n" ); document.write( "1st: 6
\n" ); document.write( "2nd: x
\n" ); document.write( "3rd: y
\n" ); document.write( "4th: 10
\n" ); document.write( "5th: 15
\n" ); document.write( "6th: 15
\n" ); document.write( "7th: 16
\n" ); document.write( "----
\n" ); document.write( "Equation:
\n" ); document.write( "Mean = (6+x+y+10+15+15+16)/7 = 11
\n" ); document.write( "-----
\n" ); document.write( "x+y + 52 = 77
\n" ); document.write( "----
\n" ); document.write( "x+y = 25
\n" ); document.write( "-----
\n" ); document.write( "Comment: x+y cannot be 25 if 10 is the median.
