    For a given distribution of marks mean is 35.16 and its standard deviation is 19.76. The co-efficient of variation is

    A)                 \[\frac{35.16}{19.76}\]          

    B)                 \[\frac{19.76}{35.16}\]

    C)                 \[\frac{35.16}{19.76}\times 100\]        

    D)                 \[\frac{19.76}{35.16}\times 100\]

    Correct Answer: D

    Solution :

                    Coefficient of variation \[=\frac{\text{S}\text{.D}\text{.}}{\text{Mean}}\times 100\]\[=\frac{19.76}{35.16}\times 100\].
