**Extracurricular activities can empower students to make their own decisions and help them gain vital experience and skills to lead them on the path to their future.

Happy Puzzle Solving 🙂 .**

**1. The Camels**

Four tasmanian camels traveling on a very narrow ledge encounter four tasmanian camels coming the other way. Tasmanian camels never go backwards, especially when on a precarious ledge. The camels will climb over each other, but only if there is a camel sized space on the other side. The camels didn’t see each other until there was only exactly one camel’s width between the two groups. How can all camels pass, allowing both groups to go on their way, without any camel reversing?

**2. The Waiter**

Three men in a cafe order a meal the total cost of which is $15. They each contribute $5. The waiter takes the money to the chef who recognizes the three as friends and asks the waiter to return $5 to the men. The waiter is not only poor at mathematics but dishonest and instead of going to the trouble of splitting the $5 between the three he simply gives them $1 each and pockets the remaining $2 for himself. Now, each of the men effectively paid $4, the total paid is therefore $12. Add the $2 in the waiters pocket and this comes to $14…..where has the other $1 gone from the original $15?

**4. The Cannibals**

Three cannibals and three anthropologists have to cross a river. The boat they have is only big enough for two people. The cannibals will do as requested, even if they are on the other side of the river, with one exception. If at any point in time there are more cannibals on one side of the river than anthropologists, the cannibals will eat them. What plan can the anthropologists use for crossing the river so they don’t get eaten? Note: One anthropologist can not control two cannibals on land, nor can one anthropologist on land control two cannibals on the boat if they are all on the same side of the river. This means an anthropologist will not survive being rowed across the river by a cannibal if there is one cannibal on the other side.

**11. The Fake Coin**

You have twelve coins. You know that one is fake. The only thing that distinguishes the fake coin from the real coins is that its weight is imperceptibly different. You have a perfectly balanced scale. The scale only tells you which side weighs more than the other side. What is the smallest number of times you must use the scale in order to always find the fake coin? Use only the twelve coins themselves and no others, no other weights, no cutting coins, no pencil marks on the scale. etc. These are modern coins, so the fake coin is not necessarily lighter. Presume the worst case scenario, and don’t hope that you will pick the right coin on the first attempt.
