1. You begin reading a book 240 pages long. If you read half of the remaining book each day how long would it take you to finish the book?
2. Add a single line to the equation in order to make it true (the 'equals' sign remains unchanged).
105 + 2 + 5 = 350
3. Forward I am heavy, but backward I am not. What am I?
4. The Burning Island
You are in the center of on a Pacific island that is a kilometre long and half a kilometre wide. The vegetation is very dry from a long drought. Suddenly it catches fire at one end of the island, and a strong wind is blowing it towards you, burning the whole width of the island. There's no beach, only steep cliffs, and the sea is full of sharks.
What can you do?
