Whereas L = Lower class boundary of the class having the mode

            f0 = Frequency of the class below the modal class

            f1 = Frequency of the class having the mode

            f2 = frequency of the class above the modal class

            c = Class interval

Hence mode = 60.50 +[(48 - 32)/{{2(48)} - 32 -27}] * 20

  = 69.14
