Solution

The correct option is A $2 \frac{3}{5}$ of an hour
Time spent on reading = $2 \frac{1}{5}$ of an hour

Time spent on writing = $\frac{2}{5}$ of an hour

To calculate the total time spent on both reading and writing, add the individual time given in the form of two mixed numbers.

For that, let's add both the fractions.

$2 \frac{1}{5} +$ $\frac{2}{5} =$ $2 +$ $\frac{1}{5} +$ $\frac{2}{5}$

= $2$ $+$ $\frac{3}{5}$

= $2 \frac{3}{5}$

∴ Raj spent $2 \frac{3}{5}$ of an hour on both reading and writing.
