If the third day of a month is Monday, which one of the following will be the fifth day from 21st of this month?

Correct Option (3)

Given that the third day of the month is Monday.

The days of the week repeat in a 7-day cycle. Therefore, Monday will occur on the following dates:

• 3rd day
• 3 + 7 = 10th day
• 10 + 7 = 17th day
• 17 + 7 = 24th day

To determine the day of the 21st of the month, we can count forward from the 17th day (Monday):

• 17th: Monday
• 18th: Tuesday
• 19th: Wednesday
• 20th: Thursday
• 21st: Friday

The question asks for the fifth day from the 21st of this month. This refers to the (21 + 5) = 26th day of the month.

Now, counting forward from the 21st day (Friday) to the 26th day:

• 21st: Friday
• 22nd: Saturday
• 23rd: Sunday
• 24th: Monday
• 25th: Tuesday
• 26th: Wednesday

Therefore, the fifth day from the 21st of the month is Wednesday.

Incorrect Options:

Options (1) Monday, (2) Tuesday, and (4) Friday are incorrect as the calculated day, following the established calendar sequence, is Wednesday.
