How many working days are there in  the month given above?

Here, we have to find the number of working days in the given month:

In the monthly calendar, weekends are considered as leave and the remaining days are working days.

The total number of days in the month is 31.

The total number of leave days is 8.

By removing the leave days from the total number of days we get the working days:

$\Rightarrow 31-8=23$

Therefore, the number of working days is $23$.

Hence, Option A is the correct answer.
