Answer:

To determine the day of the week after 61 days, we need to understand the concept of the "day of the week cycle" and how it repeats every 7 days.

Day of the Week Cycle:
The days of the week follow a cycle that repeats every 7 days. This cycle is as follows:

- Sunday
- Monday
- Tuesday
- Wednesday
- Thursday
- Friday
- Saturday

After Saturday, the cycle repeats with Sunday again.

Calculating the Day of the Week:
To calculate the day of the week after a certain number of days, we divide the number of days by 7 and find the remainder. This remainder represents the number of days that have passed within the current week.

In this case, we need to find the day of the week after 61 days.

Dividing 61 by 7:
When we divide 61 by 7, we get a quotient of 8 and a remainder of 5.

Finding the Day:
The remainder of 5 tells us that 5 days have passed within the current week. To find the day of the week, we count 5 days ahead from Monday.

- Monday (Day 1)
- Tuesday (Day 2)
- Wednesday (Day 3)
- Thursday (Day 4)
- Friday (Day 5)

Therefore, the day of the week after 61 days will be Saturday (Option B).

Conclusion:
To calculate the day of the week after a certain number of days, we divide the number of days by 7 to find the remainder. This remainder represents the number of days that have passed within the current week. Counting that many days ahead from the starting day gives us the day of the week. In this case, after 61 days, it will be Saturday.
