To solve the problem, we need to assign each of the four friends one of the different fruits based on the given conditions:
- Alice does not buy grapes.
- Bob buys neither apples nor oranges.
- Charlie does not buy bananas.
Since each person buys a different fruit and there are four fruits (apple, banana, orange, grape), we can use the process of elimination:
- Bob cannot buy apples or oranges, leaving only bananas or grapes as options.
- Charlie cannot buy bananas, so his options are apples, oranges, or grapes.
- Alice cannot buy grapes, leaving her with apples, bananas, or oranges as options.
Now we assign the fruits:
- Since Dana is not explicitly restricted and everyone else has a fruit they cannot buy, assume Dana buys grapes.
- This leaves Bob with the only choice of bananas, as he cannot buy apples or oranges.
- Charlie unable to buy bananas, cannot have grapes because Dana has them, and is now limited to apples or oranges.
- Since Alice cannot buy grapes, she must buy oranges.
- This leaves Charlie with apples, as he cannot buy bananas and oranges are with Alice
Thus, by elimination and matching individuals to their only possible fruit:
- Alice buys the orange.
- Bob buys the banana.
- Charlie buys the apple.
- Dana buys the grape.
The answer is that Alice buys the orange.
