Solution

The correct option is D $\frac{6}{35}$
$\frac{3}{7}$ of $\frac{2}{5}$ is nothing but $\frac{3}{7} \times \frac{2}{5}$ .

So, we will multiply numerator of one fraction by the numerator of other fraction and denominator of one fraction by the denominator of other fraction.

So, $\frac{3}{7} \times \frac{2}{5}$ = $\frac{3 \times 2}{7 \times 5}$ = $\frac{6}{35}$
