My Question of the Day

Correct!

• Here's Why:

  A purchase from aisles 4 through 7, inclusive, would count in both Shakira’s purchases from aisles 1 through 7, inclusive, and those from aisles 4 through 10, inclusive. So, for example, she could have bought as few as 7 items total: say 5 items from aisle 6 and 2 from aisle 9. Or the total could be as high as 12: say 5 items from aisle 1 and 7 from aisle 10. Any total number of items between 7 and 12 is also possible. In particular, Shakira could have bought 9 items total (for example, 2 items from aisle 1, 3 from aisle 6, and 4 from aisle 10), 10 items total (for example, 3 items from aisle 1, 2 from aisle 6, and 5 from aisle 10), or 11 items total (for example, 4 items from aisle 1, 1 from aisle 6, and 6 from aisle 10). Therefore, the correct answer is I, II, and III.
