Show answer & explanation
Correct answer: C
Goal: Find the number of gift boxes sold on Monday.
Statement I analysis: Monday = Sunday × 1.10, but the number sold on Sunday is not given. A percentage increase alone does not give the absolute number, so this statement alone is insufficient.
Statement II analysis: With 1500 visitors on Sunday and every third visitor buying a box, Sunday sales = 1500 ÷ 3 = 500 boxes. This provides Sunday’s absolute number but does not tell Monday’s sales, so this statement alone is insufficient.
Combined analysis: Using Sunday = 500 (from Statement II) and Monday = 10% more than Sunday (from Statement I), Monday sales = 500 × 1.10 = 550 boxes. Both statements together are sufficient to determine Monday sales.
Conclusion: Both statements together are required and sufficient to find Monday sales, which equal 550 boxes. The provided set of answer choices does not include the correct option indicating that both statements together are sufficient.
