A watch is 1 minute slow at 1 p.m. on Tuesday and 2 minutes fast at 1 p.m. on Thursday. When did it show the correct time?

Solution

✅ Correct Option: 1

The watch moves from 1 minute slow to 2 minutes fast, gaining 33 minutes over the 4848 hours from Tuesday 1 p.m. to Thursday 1 p.m. Gaining the first 11 minute takes 48×(1/3)=1648 \times (1/3) = 16 hours. Adding 16 hours to Tuesday 1 p.m. gives 5 a.m. on Wednesday.
