Answer:

Option(a) - 22

Step-by-step explanation:

CI               frequency    Midvalue(xi)   fixi

0-10               12                5                   60

10-20            16                15                  240

20-30            6                25                 150

30-40            7               35                  245

40-50           9               45                   409

                  ----                                     -------

               ∑fi = N = 50                            ∑fixi =  1104

We have to calculate Mean of the following data.

Mean = ∑fixi/∑fi

        = 1104/50

        = ~22.

Hence, Mean = 22.
