Explanation

Here's a brief explanation: 1. **Determine the target date:** The phrase "fifth day from 21st of this month" usually implies counting the 21st as the first day. So, the days would be 21st (1st), 22nd (2nd), 23rd (3rd), 24th (4th), 25th (5th). Therefore, we need to find the day of the week for the 25th of the month. 2. **Calculate the day for the 25th:** * We are given that the 3rd day of the month is Monday. * Days of the week repeat every 7 days. * If the 3rd is Monday, then: * 3 + 7 = 10th is Monday * 10 + 7 = 17th is Monday * 17 + 7 = 24th is Monday * Since the 24th is Monday, the next day, the 25th, will be Tuesday. 3. **Match with options:** The 25th is Tuesday, which corresponds to Option B. The final answer is B) Tuesday.
Logical Reasoning: If the 3rd day of a month is Monday, which one of the following will be the fifth day from 21st of this month?
