The following measures were computed for a non-symmetrical frequency distribution: mean = 50, coefficient of variation = 35% and Karl Pearson's coefficient of skewness of first type= -0.25. The value of mode of the distribution is:

A

$$\frac{1235}{24}$$

B

$$\frac{835}{24}$$

C

$$\frac{835}{16}$$

D

$$\frac{435}{8}$$
