These riddles really made me think:
1. A man builds a square house, every side facing south. A big bear walks by. What colour is the bear?
2. Some months have 30 days, some have 31. how many have 28?
3. You have two coins totalling 11 pence. One of the coins is not a 10 pence piece. What are the 2 coins?
4. If two monkeys sit in the corner of a square room and look at another pair in another corner, and so on until four pairs of monkeys are looking at other pairs, how many monkeys could say they were looking at other monkeys?
I'm rubbish at solving riddles, hopefully you'll do better than me. 🙄
