Suppose today is Friday, what day of the week will it be 65 days from ...
The day of the week repeats every 7 days.
Given today is Friday. Again Friday is repeated on the 7th day, 14th,... on 7 multiple days.

Suppose today is Friday, what day of the week will it be 65 days from ...
Question Analysis:
The question asks us to determine the day of the week that will be 65 days from today, given that today is Friday. We need to calculate this without using any external sources or tools.
Solution:
To solve this problem, we can use the concept of modulo arithmetic. Modulo arithmetic is a system of arithmetic for integers, where numbers wrap around when reaching a certain value.
Identifying the Day of the Week:
To determine the day of the week, we need to find the remainder when dividing the number of days by 7. This remainder will correspond to a specific day of the week.
Calculating the Remainder:
Given that today is Friday, we can start counting from 0. We need to find the remainder when adding 65 days to this starting point.
65 divided by 7 gives us a quotient of 9 and a remainder of 2. This means that after 9 weeks (63 days), we will have 2 extra days.
Determining the Day:
Adding the remainder of 2 days to Friday, we get Sunday. Therefore, 65 days from today will be Sunday.
Conclusion:
The correct answer is option 'b', Sunday. After 65 days, starting from today (Friday), we will reach Sunday.
