Turn on the first two switches. Leave them on for 5 minutes. Once 5 minutes has passed, turn off the second switch, leaving one switch on. Now go through the door.

Question #09
You are in a cookie factory, and need to make a huge batch of chocolate chip cookies. The recipe calls for exactly 4 cups of sugar. Problem is that you have two buckets. One bucket holds 5 cups, the other 3 cups. Using these buckets, how can you measure exactly 4 cups of sugar.

Answer:
This is possible, and there are two ways to do it:
Solution 1: Fill the 3-cup bucket and pour it into the 5-cup bucket. Fill the 3-cup bucket again, and pour it into the 5-cup bucket until the 5-cup bucket is full. That will leave exactly 1 cup of sugar in the 3-cup bucket. Dump out the 5-cup bucket, and dump the 1 cup from the 3-cup bucket into the empty 5-cup bucket. This leaves 1 cup in the 5-cup bucket. Now fill the 3-cup bucket again and add it to the 5-cup bucket. Now you have exactly 4 cups of sugar in the 5-cup bucket!Solution 2: Fill the 5-cup bucket. Pour it into the 3-cup bucket. This leaves 2 cups in the 5-cup bucket. Dump out the 3-cup bucket. Now pour the 2 cups from the 5 cup into the 3 cup. Refill the 5 cup. Now pour the 5 cup into the 3 cup until the 3 cup is full. That will leave exactly 4 cups in the 5-cup bucket!

Question #10
A man is the owner of a winery who recently passed away. In his will, he left 21 barrels (seven of which are filled with wine, seven of which are half full, and seven of which are empty) to his three sons. However, the wine and barrels must be split, so that each son has the same number of full barrels, the same number of half-full barrels, and the same number of empty barrels. Note that there are no measuring devices handy. How can the barrels and wine be evenly divided?

Answer:
Two half-full barrels are dumped into one of the empty barrels. Two more half-full barrels are dumped into another one of the empty barrels. This results in nine full barrels, three half-full barrels, and nine empty barrels. Each son gets three full barrels, one half-full barrel, and three empty barrels.
