Food for your Brain

Mom asked me some puzzles/riddles as part of the summer fun. Let me relay them to you. Try to solve them. Oh, yeah! I did solve them, ofcourse with some clues. I shall post the answers in a separate post in couple of days, so you won't get tempted to peek at the answers. Here you go:

1. There were 26 crows on a fence. A hunter shot 8 of the birds with a single bullet. How many crows would be left on the fence?

2. There were an elephant and an ant. They were very good friends. But they both had a bad habit of lying. The elephant would lie only on every Monday, Tuesday, Wednesday. The ant would lie only on every Thursday, Friday, Saturday. The rest of the days they speak only the truth.
Oneday, the elephant told the ant, "I lied Yesterday!" The ant immediately said, "I too!"
Which day did this conversation happen?

3. A boy has 2 US coins of which one is NOT a nickel. The sum of the coins is 30cents. Can you find what are those 2 coins?

4. A Tiger, an elephant and an ant were standing in a queue (in the same order) to get their hot lunch in their school cafeteria. The tiger looked back and said, "There are 2 more animals standing behind me". The elephant looked back and said, " There is one animal behind me". The ant looked back and said, "There is one animal behind me". Can you explain how that is possible?

5. A boy was challenged by his friends to stay inside a room for exactly 30 mins. He was given a stick and a match box. The stick will take 1 hr to completely burn. The boy has to come out exactly after 30 mins. He doesn't have a watch/clock to know when it is time to come out. All he has is the stick and a match box to light it. How will he know when to come out?

Mom could only recall these puzzles from her childhood. :-) Hope you have fun solving them as a summer treat.
