Show the answer and the worked solution
Correct answer: B. Saturday
Worked solution
- 61 ÷ 7 = 8 remainder 5, so 5 odd days.
- Five days after Monday: Tuesday, Wednesday, Thursday, Friday, Saturday.
Answer: Saturday.
The idea
Only the remainder on division by 7 matters. Count that many days forward from the given day.
Shortcut. 63 is a multiple of 7, so 61 days is 9 weeks minus 2 days: two days before Monday is Saturday.
Common trap. "Friday" — getting the remainder 5 but counting Monday itself as the first of the five days (Monday to Friday) instead of starting from Tuesday.
