Solution:

You can solve this question with two different methods. However, we are just providing one of them. If you can think of the other solution then it's great.

The man will take the goat with him and will leave the wolf and cabbage. Then he will return back leaving the goat on the other end. Now he will take the cabbage and will row towards the other end. He will leave the cabbage there and bring goat back along with him. Then he will take the wolf and leave the goat there. After leaving the wolf with cabbage on the other end, he will return back and will take the goat with him to the other end.

Solution:

Let us analyze the statements given by Peeta, Eugene and Harry.

If Peeta is right by saying that there are at least four Rembrandt, then Harry will also be right (he said that there is at least one).

If Harry is right by saying that there is at least one Rembrandt, then Peeta and Eugene will also be right.

In that case, only Eugene's statement can be true that Leonardo has less than four Rembrandt and that too in the case that he has no painting of Rembrandt at all (otherwise, Harry's statement will be true as well).

Thus Leonardo has no painting of Rembrandt at all.

Solution:

Let us analyze the statements. If 1 is correct, then 2 will be correct too. If suppose 2 is correct, then 3 will also be correct. Now the question says that there can be only one correct answer. We know that 1 and 2 cannot be the answer as if they are correct, they will not be correct alone. But if 3 is correct it will not contradict with the situation.

Thus 3 is the correct answer.
