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
