[ Puzzle ]
1. How do we measure forty-five minutes using two identical wires, each of which takes an hour to burn? We have matchsticks with us. The wires burn non-uniformly. For example, the two halves of the wire might burn in 10 minutes and 50 minutes, respectively.
2. There are 4 people (A, B, C, and D) who want to cross a bridge at night.
A, B, C and D take 1, 2, 5 and 8 minutes respectively to cross the bridge.
There is only one torch with them, and the bridge cannot be crossed without the torch.
There cannot be more than two people on the bridge at any time, and when two people cross the bridge together, they must move at the slower person's pace. Find the minimum time required to cross the bridge.
3. You are given a normal die and a blank die. (Each die is six-sided and equally likely to show each face). Label the blank die using the numbers 0 to 6 so that when you roll the two die the sum shows each whole number from 1 to 12 with equal chance. You can use a number more than once, or not at all, so you could label the faces 1, 2, 3, 4, 4, 5. But you do have to label all six faces of the blank die.
