In a month of 31 days, third Friday falls on 17th. What will be the last day of the month?
Answer & explanation
Correct answer: option 2
The correct answer is Option (2) → 5th Friday
The same day of the week comes back every 7 days, so the Fridays of the month are found by counting back and forward from the 17th in steps of 7.
Third Friday: 17th, so the second is the 10th and the first is the 3rd
Fourth Friday: \(17+7=24\)th
Fifth Friday: \(24+7=31\)st, the last day of a 31-day month
