Question

- Wednesday
- Thursday
- Friday
Show the answer and the worked solution
Correct answer: D. Friday
Worked solution
- E = Monday, C = Wednesday, D = Thursday (immediately after C).
- Tuesday and Friday remain for A and B.
- A must visit before B, so A = Tuesday and B = Friday.
Answer: Friday.
The idea
Place the fixed days first, then use the ordering clue to break the tie between the remaining slots.
Shortcut. B cannot take the earlier of the two free days, since A comes first; with Monday, Wednesday and Thursday taken, the later free day is Friday.
Common trap. "Tuesday" — swapping A and B, reading 'A visits before B' as B visiting first.
