Show answer & explanation
Correct answer: B
Answer: Wednesday
Explanation:
Rest days occur every 9th day (he works 8 days and rests on the 9th). Therefore the 12th rest day is on day 9 × 12 = 108.
To find the weekday, treat day 1 as Monday. Compute (108 − 1) mod 7 = 107 mod 7 = 2.
A remainder of 2 means the day is two days after Monday, which is Wednesday.
