0-100             50                           12            -2              -24

100-200        150                          16            -1               -16

200-300       250                          6             0                0

300-400       350                           7             1                 7

400-500       450                           9            2                18

total                                               50                             -15

mean=A+∑fiui/ ∑fi ×ht

       =  250+(-15)/50 ×100

       =  250-30

mean =  220
