 CI        F    CF
 0-10     5      5                   45+x+y=60             M= l+(N/2+CF)/f x h
10-20   x      5+x                x+y=15--1           M=28.5,N=60 and N/2=30,
20-30   20    25+x                                        30 lies between 25+x and 40+x
30-40   15    40+x                          so take 25=x as CF and the value of the F of 
40-50    y     40+x+y                      your greater CF is 15 so F=15,l=30 (the lower 
50-60    5     45+x+y                   limit straight the F value, h=10 . substitute the 
  total-  60                      values and x=8 and y=7
