OK, a couple or four logic puzzles to solve:
1. There are three switches downstairs. Each corresponds to one of the three light bulbs in the attic. You can turn the switches on and off and leave them in any position.
How would you identify which switch corresponds to which light bulb, if you are only allowed one trip upstairs?
2. How many times can you subtract the number 2 from the number 32?
3. If you had a 5-litre bowl and a 3-litre bowl, and an unlimited access to water, how would you measure exactly 4 litres?
4. The day before yesterday I was 25 and the next year I will be 28. This is true only one day in a year. What day is my birthday?
