This is somewhat complex problem. It needs vary high logical reasoning. It is the basic in the field of AI(Artificial Intelligence). It goes like this

I will provide you equation with three words. Assign numerical values to each letters of the words such that the equation comes true. For Example

SEEN+SOME=>BONES
if you assign 5778 to SEEN and 5097 to SOME the value of BONES becomes 10875. Here all the alphabets are assigned one unique value.

I want you to try to apply logic for this case.

James and his fishing rod

James ordered a fishing rod, priced at $3.56. Unfortunately, James is an Eskimo who lives in a very remote part of Greenland and the import rules there forbid any package longer than 4 feet to be imported.

The fishing rod was 4 feet and 1 inch, just a little too long, so how can the fishing rod be mailed to James without breaking the rules? Ideally James would like the fishing rod to arrive in one piece! Means that you can't cut the rod from anywhere.

13 people came into a hotel with 12 rooms and each guest wanted his own room. The bellboy solved this problem.
He asked the thirteenth guest to wait a little with the first guest in room number 1. So in the first room there were two people. The bellboy took the third guest to room number 2, the fourth to number 3, ..., and the twelfth guest to room number 11. Then he returned to room number 1 and took the thirteenth guest to room number 12, still vacant.
How can everybody have his own room?
