Crossing the River
A farmer is trying to cross a river. He is taking with him a rabbit, carrots and a fox, and he has a small raft. He can only bring 1 item a time across the river because his raft can only fit either the rabbit, the carrots or the fox. How does he cross the river. (You can assume that the fox does not eat the rabbit if the man is present, you can also assume that the fox and the rabbit are not trying to escape and run away) 3 minutes
The key is realizing that you have to take the rabbit over first and then switch the fox with the rabbit. See step 2.
Step 1
Take the rabbit to the other side
Shore Other Side
Carrots, Fox Rabbit
Step 2
Go back and get the Fox and switch it with the Rabbit
**The key here is that the carrots and the rabbit are not being left alone.
Shore Other Side
Carrots Fox
Rabbit (Not left alone)
Step 3
Take the carrots across
Shore Other Side
Rabbit Fox, Carrots
Step 4
Go back and get the rabbit
Shore Other Side
Rabbit, Fox, Carrots

Three lawers rent a hotel room for the night. When they get to the hotel they pay the $30 fee splitting it evenly among each of them, then go up to their room. Soon the bellhop brings up their bags and gives the lawyers back $5 because the hotel was having a special discount that weekend. So the three lawyers decide to each keep $1 of the $5 and to give the bellhop a $2 tip. However, when they sat down to tally up their expenses for the weekend the could not explain the following details:
Each one of them had originally paid $10 (towards the initial $30), then each got back $1 which meant that they each paid $9. Then they gave the bellhop a $2 tip.
HOWEVER, (3)($9) + $2 = $29 What happened to the other dollar?
2 minutes
What is nothing?
They did NOT spend (3)($9) + $2 = $29
They spent exactly $27 dollars. $25 for the room and $2 for the tip. Remember they got exactly $3, in total back.
Another way to think about the answer is to just pretend that the bellhop refunded $3 to the lawyers (rather than giving them $5 and receiving $2 back).
If the lawyers get $3 back and each takes $1. They they spent exactly $27 dollars.

If I borrow $50 from my mother and $50 from my father, that's $100. I buy a blue coat that is $97. I have $3 change so I give $1 to my mother, $1 to my father and keep $1. I owe my mother $49 and my father $49, together that is $98. Plus the one dollar I kept is $99. Where is the other dollar?
2 minutes
There is no missing dollar! You started with $100 and spent $97. With the $3 left, you gave $1 to mom, $1 to dad, and kept $1. You owe them $98 but kept $1, which you can count towards what you owe them. So, you need $97 more to pay them back (cost of shirt)!

How can you add eights 8's to get the number 1,000 for an answer. You can use the 8's as part of any number but the number can only use 8's eg 88
3 minutes
What is 888 + 88 + 8 + 8 + 8?
Key is that 1,000 ends in 0 so there needs to be 5 8's added together. That only leaves three 8's to put elsewhere.
