If the 31st day of a month is a Friday, what was the day on the 3rd day of that month?
Answer & explanation
Correct answer: option 2
The correct answer is Option (2) → Friday
The days of the week repeat every 7 days, so dates that differ by a multiple of 7 fall on the same day.
From the 3rd to the 31st: \(31-3=28\) days
\(28=4\times7\), 4 whole weeks with no day left over
So the 3rd falls on the same day as the 31st: Friday
