Surprise Birthday Party Riddle
David is throwing Robert a surprise birthday party but he has to stay within his budget. He spent half of his money plus $2.00 on the cake. Half of what he had left plus $2.00 was spent on balloons and streamers. Then he spent half of what he had left plus $1.00 on candy. Now he is out of money, how much did he start with?
Hint:
This one is best solved working backwards, the last part David spent half of what was left plus $1.00 on candy and then was out of money. That means he must have spent $2.00 on Candy as $1.00 was half of what he had using the same logic backwards: $2.00 on candy $6.00 on Balloons and Streamers $12.00 on the cake Total of $20.00.

Who Is The Engineer Riddle
A train goes between Chicago and New York. The brakeman, the fireman and the engineer are named Smith, Jones and Brown. (The names are not necessarily in order). There are also three passengers named Mr. Smith, Mr. Jones and Mr. Brown. Mr. Brown lives in New York. The brakeman lives halfway between New York and Chicago. Mr. Jones earns exactly $20,000 per year. Smith beat the fireman at their last game of golf. The passenger who lives in Chicago has the same name as the brakeman. The brakeman's next door neighbor is a passenger on this train and earns exactly three times as much as the brakeman. What is the name of the engineer?
Hint:
Determine the known facts. Also notice that the passengers are noted with the title Mr., where as the brakeman, engineer and fireman are identified by their last names only. 1. Mr Brown Lives in New York City 2. The brakeman lives midway between NY and Chicago 3. Mr. Jones earns exactly $20K per year 4. Smith beat the fireman at their last game of golf. 5. The brakeman's next-door neighbor, who is a passenger, earns exactly three times the brakeman's salary. 6. The passenger who lives in Chicago has the same name as the brakeman. According to #1 and #2, the brakeman's neighbor cannot be Mr. Brown. According to #5, the brakeman's neighbor also cannot be Mr. Jones, because $20,000 is not evenly divisible by three. This leaves Mr. Smith as the next door neighbor to the brakeman. Mr. Smith lives halfway between New York and Chicago (#2) as does the brakeman. Since Mr. Brown lives in New York, by process of elimination, it is now known that Mr. Jones lives in Chicago. According to statement #6, this means that the brakeman is named Jones. According to statement #4, the fireman cannot be Smith, so the fireman must be must be Brown, which leaves Smith as the engineer. Did you answer this riddle correctly?

Outrunning A Train Riddle
Walking home one day, you take a short cut along the train tracks. The tracks cross a narrow bridge over a deep gorge. At the point you are 3/8 of the way across the bridge, you hear the train whistle somewhere behind you. You charge across the bridge, and jump off the track as the train is about to run you down. As it happens, if you had gone the other way, you would have reached safety just before being run over as well. If you can run ten miles per hour, how fast is the train moving?
Hint:
The train is moving at 40 miles per hour. Imagine that a friend is walking with you. When the train whistle blows, you head away from the train, he heads toward it. When he reaches safety, you will be 6/8 (or 3/4)of the way across the bridge, and the train will have just reached the bridge. For the train to cross 4/4 of the bridge in the time you cross the remaining 1/4, the train must be moving four times your speed. Did you answer this riddle correctly?
