For a given distribution of marks, the mean is 35.16 and its standard deviation is 19.76.The coefficient of variation ??...Experts please answer it.

Dear student,
                      According to the question
                     coefficient of variation=   $\frac{\mathrm{standard} \mathrm{deviation}}{\mathrm{Mean}}\times 100$
                                      =   $\frac{19.76}{35.16}\times 100$
                                      =    56.2
thank you.
