    If \[L=50,{{\Delta }_{1}}=8,{{\Delta }_{2}}=12\]and \[C=5\], then find the mode of the data; where \[{{\Delta }_{1}}={{f}_{m}}-{{f}_{m-1}}\] and \[{{\Delta }_{2}}={{f}_{m}}-{{f}_{m+1}},{{f}_{m}}=\] frequency of modal class, \[{{f}_{m-1}}=\] frequency of class before modal class, \[{{f}_{m+1}}=\] frequency of class after modal class, C = class width.

    A)  48                               

    B)  52

    C)  53.5                            

    D)  54

    Correct Answer: B

    Solution :

    (b): Mode \[=L+\left( \frac{{{\Delta }_{1}}}{{{\Delta }_{1}}+{{\Delta }_{2}}} \right)C\]
