Question

Who cleans his home on Sunday ?

• A. The person who likes Green
• B. The friend whose name is A
• C. Teacher
• D. Plumber
• E. The person who likes Red

Hint:

After filling the ``definite'' day assignments (Teacher=Friday, Hotelier=Saturday, Electrician=Thursday), eliminate remaining days for each person using the ``not'' constraints to find who gets Sunday.

Answer 1

The Correct Option is D

Step 1: Concept Analysis:
Using the full solution table from the puzzle passage, determine who cleans on Sunday.

Step 2: Solution Approach:
Assigned days: Teacher = Friday, Hotelier = Saturday, Electrician = Thursday (consecutive with Teacher), Black-liker = Thursday = Electrician. Remaining days: Mon, Tue, Wed, Sun for Doctor(B), Retired, Lawyer, Plumber. B(Doctor) $\neq$ Monday or Saturday; Plumber $\neq$ Saturday or Thursday. Working through: Plumber(A) is assigned Sunday. Teacher likes Green (not A); Electrician likes Red (not G,E). This places Plumber(A) on Sunday.

Step 3: Conclusion:
The Plumber cleans his home on Sunday.
