0 - 20                   5                        10               -2                         -10

20-40                   11                        30              -1                         -11

40-60                   13                       50               0                         0

60-80                   7                         70               1                          7

80-100                  8                        90               2                         16

100 - 120               6                        110               2                         12

          Total           50                                                                     14

Mean = 50  + 20 * 14/50
