Question

If the 29th of a month is Friday, then what day would be on the 5th of the same month?

• A. Monday
• B. Tuesday
• C. Wednesday
• D. Friday

Hint:

To find days across the month, use modulo 7 (days of the week) and count forward or backward carefully.

Answer 1

The Correct Option is A

Step 1: Count the number of days backward from 29th to 5th. From 29th to 5th: \[ 29 - 5 = 24 \text{ days back} \]
Step 2: Calculate how many complete weeks and remainder days. \[ 24 \div 7 = 3 \text{ weeks and } 3 \text{ days} \] So, we go back 3 days from Friday.
Step 3: Go back 3 days from Friday: \[ \text{Friday} \rightarrow \text{Thursday} \rightarrow \text{Wednesday} \rightarrow \boxed{\text{Monday}} \]
