If second Saturday and every alternate Saturday after that in a month and all Sundays are holidays, then how many working days are there in a 30 day month beginning on a Saturday?A20B21C22D23

Sure, let's break it down:

1. Identify the holidays: The month starts on a Saturday, so the second Saturday falls on the 8th day of the month. Every alternate Saturday after that would be the 22nd day of the month. So, there are 2 Saturdays that are holidays.

2. Count the Sundays: Since the month starts on a Saturday, the next day, Sunday, is the 2nd day of the month. Then, every 7th day after that would be a Sunday. So, the Sundays fall on the 2nd, 9th, 16th, 23rd, and 30th days of the month. So, there are 5 Sundays that are holidays.

3. Calculate the total holidays: There are 2 Saturdays and 5 Sundays that are holidays, so there are a total of 2 + 5 = 7 holidays.

4. Subtract the holidays from the total days in the month: There are 30 days in the month, so if you subtract the 7 holidays, you get 30 - 7 = 23 working days.

So, the answer is D23.
