Let's analyze the problem step-by-step.
Given:
- Month length: 30 days
- Month starts on: Saturday
- Holidays: every second Saturday and all Sundays
- Need to find: number of working days in the month
Step 1: Identify all Saturdays and Sundays in the month
Since the month starts on a Saturday:
- Day 1: Saturday
- Day 2: Sunday
- Day 3: Monday
- Day 4: Tuesday
- Day 5: Wednesday
- Day 6: Thursday
- Day 7: Friday
- Day 8: Saturday
- Day 9: Sunday
- ... and so on.
Saturdays in the month:
- 1, 8, 15, 22, 29
Sundays in the month:
- 2, 9, 16, 23, 30
Step 2: Determine which Saturdays are holidays
- Every second Saturday is a holiday.
- Saturdays: 1, 8, 15, 22, 29
- Second Saturdays: 8, 22 (2nd and 4th Saturdays)
So, holidays on Saturdays are days 8 and 22.
Step 3: All Sundays are holidays
- Sundays: 2, 9, 16, 23, 30
- All these are holidays.
Step 4: Calculate total holidays
- Saturdays holidays: 2 days (8, 22)
- Sundays holidays: 5 days (2, 9, 16, 23, 30)
- Total holidays = 2 + 5 = 7 days
Step 5: Calculate working days
- Total days in month = 30
- Holidays = 7
- Working days = 30 - 7 = 23 days
Final Answer:
There are 23 working days in the month.
