    Pinocchio Paradox Riddle

    Hint:
    His nose did grow when he said it would, but his nose is only supposed to grow when he lies, and his nose would grow even though he told the truth, and the paradox appears to exist again.

    You can prove that's not true because he created a self fulfilling prophecy when he said his nose was going to grow bigger because saying that was saying he was going to lie.

    In order to lie; he had to tell the truth, and say that he was lying, when he was really telling the truth, which would be a lie.

    He did say he was lying because he said his nose was going to grow, and even though he said he was lying, he was actually telling the truth; which means he was lying about lying, or lying about not telling the truth.

    His nose did grow, and he did tell the truth, but he said he was lying when he was telling the truth, which was the lie that made his nose grow.

    Since his nose didn't grow after he told the truth, but after he lied about not telling the truth; the paradox doesn't exist.

    That second answer actually works for both scenarios, where as the first answer only works for the first scenario, so I suppose you can say the second answer is the correct one.

    Rope Burn Riddle

    Hint: You can light multiple ends and/or multiple ropes at the exact same time.
    Light both ends of one rope, and only one end of the other rope. This will cause the first rope to burn out in 30 minutes. When the first rope burns out, there will be 30 minutes left on the second rope. So then, light the other end of the second rope, and the rest of it will burn out in 15 minutes. 30 + 15 = 45 minutes.

    Fruit Friends Riddle

    Hint:
    She will always need to give you 5 apples. You both need at least 5 apples to begin with, but apart from that it doesnt matter exactly how many you each have. When she gives you 5 you will have 10 more than her because she will lose 5 and you will gain 5, resulting in a net difference of 10.

    For example, if you each have 25 apples and she gives you 5 of hers, she will be left with 20 and you will now have 30, precisely 10 more than she has.
