Solution

The correct option is A
5

$\frac{3}{5}$ $\div$ ( $\frac{15}{50}$ of $\frac{2}{5}$ )

= $\frac{3}{5}$ $\div$ $\frac{3}{25}$

{ $∵$ $\frac{15}{50}$ of $\frac{2}{5}$ = $\frac{15}{50}$ $\times$ $\frac{2}{5}$ = $\frac{3}{25}$ }

= $\frac{3}{5}$ $\times$ $\frac{25}{3}$

( Taking reciprocal of the second fraction and multiplying)

= 5
