madham - as the first two answers have already stated, the correct answer is that Ned ate it. There is not need for you to stay in suspense, because we have already worked it out. In order to work out the correct answer, all you have to do is
1. assume Linda ate it, and work out how many of the statements are true and false;
2. assume Mike ate it, and work out how many of the statements are true and false;
3. assume Ned ate it, and work out how many of the statements are true and false;
4. assume Olive ate it, and work out how many of the statements are true and false.
The assumption that Ned ate it is the only one which leads to 1 true statement and 3 false statements, so that must be the correct one. (The other three assumptions all lead to more than one true statement, so they contradict the information given in the question).

I'm going to be contrarian and pedantic here. I think Linda ate it. The only objectively true statement is Ned's denial that it was him, as he knows it wasn't. Olive's statement that Mike is lying is not objectively true, since neither of them knows who ate the slice -Mike is guessing not lying. If Mike ate it, then both Linda's and Ned's statements would be true. If Olive ate it, then both Mike's and Ned's statements would be true. If Ned ate it, then nobody's statment would be true.
