Dropping Coconuts Riddle
You have two coconuts and you want to find out how high they can be dropped from a 100 story building before they break. But you only have $1.40 and the elevator costs a dime each time you ride it up (it's free for rides down).
How can you drop the coconuts to guarantee you will find the lowest floor they will break at, while starting and ending at floor 1?
How can you drop the coconuts to guarantee you will find the lowest floor they will break at, while starting and ending at floor 1?
Hint: They break when dropped from the same height and they don't weaken from getting dropped.
You could drop it at floor 1 first (because you start at floor 1). Then you would go to the floors: 14, 27, 39, 50, 60, 69, 77, 84, 90, 95, 99, and 100. Whatever floor your first coconut breaks at, go to the floor above the last floor the coconut survived and drop the second coconut from this floor. Then go up by one floor until the second coconut breaks and that is the lowest floor it will break at. Did you answer this riddle correctly?

Bat And Ball Riddle
If a baseball and a bat cost $1.10 together, and the bat costs $1.00 more than the ball, how much does the ball cost?
Hint: The answer isn't 10 cents.
Here's the solution:
Although $1.00 + $0.10 does equal $1.10, if you take $1.00 $0.10 you get $0.90, but the problem requires that the bat costs $1 more than the ball.
So, the ball must cost $0.05, and the bat must cost $1.05 since $1.05 + $0.05 = $1.10
---
Still not convinced? You can use algebra to solve the problem:
First, lets set up the equation:
x + ($1.00 + x) = $1.10
$1.00 + 2x = $1.10
2x = $1.10 $1.00
2x = $0.101
Finally, solve for x:
x = $0.05
Check your work:
x + ($1.00 + x) = $1.10, so
$0.05 + ($1.00 + $0.05) = $1.10 Did you answer this riddle correctly?

100 Blank Cards Riddle
Someone offers you the following deal:
There is a deck of 100 initially blank cards. The dealer is allowed to write ANY positive integer, one per card, leaving none blank. You are then asked to turn over as many cards as you wish. If the last card you turn over is the highest in the deck, you win; otherwise, you lose.
Winning grants you $50, and losing costs you only the $10 you paid to play.
Would you accept this challenge?

Winning grants you $50, and losing costs you only the $10 you paid to play.
Would you accept this challenge?
Hint: Perhaps thinking in terms of one deck is the wrong approach.
Yes!
A sample strategy:
Divide the deck in half and turn over all lower 50 cards, setting aside the highest number you find. Then turn over the other 50 cards, one by one, until you reach a number that is higher than the card you set aside: this is your chosen "high card."
Now, there is a 50% chance that the highest card is contained in the top 50 cards (it is or it isn't), and a 50% chance that the second-highest card is contained in the lower 50. Combining the probabilities, you have a 25% chance of constructing the above situation (in which you win every time).
This means that you'll lose three out of four games, but for every four games played, you pay $40 while you win one game and $50. Your net profit every four games is $10.
Obviously, you have to have at least $40 to start in order to apply this strategy effectively. Did you answer this riddle correctly?
YES NO

Baseball Bat And A Ball Riddle
A baseball bat and a ball cost $1.10 together, and the bat costs $1.00 more than the ball, how much does the ball cost?
Hint:
The ball costs 5c. Not 10c. One dollar more than 10c is $1.10, $1.10 + 10c is $1.20 One dollar more than 5c is $1.05. The sum of which is $1.10. Did you answer this riddle correctly?

McDonalds Riddle
A brainteaser involving what looks like some simple math with McDonald's burgers and fries has left people starving for the correct answer. Can you solve this McDonalds riddle?
Hint: The key is to first determine how much each item is worth. The drink is clearly worth 10, and it's apparent from the second line that the burgers are worth five.
Pictures of the fries are each worth two, but you have to keep in mind that each individual packet of fries is worth one when you get to the next line. That has baited people into thinking, incorrectly, that the last line is 5 + 2 x 10.
The fourth line has also thrown many people off because it involves order of operations after already including the tricky single packet of fries.
Multiplication comes before addition, so you have to multiply one packet of fries by one drink and then add that to one burger. Thus, 5 + (1x10) = 15. Did you answer this riddle correctly?
YES NO
