Question

Three employees-X, Y, Z-are assigned to three projects-P1, P2, P3. Each project gets one employee. X cannot work on P2. Y cannot work on P3, who works on P3?

• A. X
• B. Y
• C. Z
• D. Cannot be determined

Hint:

For follow-up assignment questions, use previous assignments to reduce possibilities and confirm with remaining constraints.

Answer 1

The Correct Option is A

- Step 1: Recall constraints. X not on P2. Y not on P3. Each project gets one employee. 
- Step 2: Use Question 23 solution. Z is on P2. 
- Step 3: Assign P3. Y cannot be on P3, so P3 is X or Z. Since Z is on P2, P3 must be X. 
- Step 4: Assign P1. P1 gets Y (only remaining employee). 
- Step 5: Verify. Assignment: X-P3, Y-P1, Z-P2. Constraints: X not on P2 (satisfied), Y not on P3 (satisfied). 
- Step 6: Final conclusion. Option (1) X is the correct answer.
