The Ball Pyramid Riddle
Hint:
30
Explanation:
It's very difficult to count an actual number of balls but it can be counted mathematically as illustrated below.
Balls in lowest level most level, say level 1 : 4 * 4 = 16
Level2 => 3 * 3 = 9
Level3 => 2 * 2 = 4
Leve4 => 1
Summing up 16+9+4+1 = 30. Did you answer this riddle correctly?
YES NO

Squaring Up Riddle
Hint:
17
Explanation:
Let us say that the smallest of the square is of 1 unit side.
We have 6 such squares. Now moving up, if we see the squares with side 2 units, we have 8 of them. Similarly we have 2 squares with side 3 units and 1 square with side 4 units.
6 + 8 + 2 + 1 = 17 squares. Did you answer this riddle correctly?

Finding The Angles
Hint:
47
Explanation:
At first look, it seems pretty easy but on the contrary, it is pretty tricky a question. So let us simplify it by dividing the triangle into three equal triangles (the triangles so formed if outer side is connected to the center of the circle) and then count the number of triangles in each part by taking two or more parts together.
First, let us take the triangles in one part. There are 4 non-overlapping and 3 overlapping triangles.
4 + 3 = 7
7 * 3 = 21
Next, if we take number of triangles by taking two parts together, there are 8 in total.
8 * 3 = 24
Lastly, the number of triangles if all three parts are taken together, there are a total of 2.
21 + 24 + 2 = 47. Did you answer this riddle correctly?
YES NO

You and your wife organize a dinner party. You invite four other husband-wife couples. You and your wife don't necessarily know everyone you invited. Once everyone is at the party, the people who don't know each other yet shake hands with each other. You can assume that everyone knows their own wife/husband, and that no one shakes their own hand.

How many people did your wife shake hands with?
Hint:
Your wife shook hands with 4 people
If everybody shook hands with a different number of people, then the most any person shook hands with was 8 people, and in fact, a single person must have shaken hands with exactly 8 people. Figure out exactly who this person did - and didn't - shake hands with. Then go from there. Did you answer this riddle correctly?

A Lady Steals $100
How smart are you?.....A lady walks in the store and steals $100 bill from the register without the owners knowledge. She comes back 5 mins later and buys $70 worth of goods with the $100 bill. The owner gives her $30 in change, how much did the owner lose????
A. $30
B. 70
C. $100
D. $130
E. $170
F. $200
DO NOT OVER THINK IT!
A. $30
B. 70
C. $100
D. $130
E. $170
F. $200
DO NOT OVER THINK IT!
Hint:
The best answer from the choices is the owner lost $100. The $100 bill that was stolen was then given back to the owner. What the owner loses is the $70 worth of goods and the $30 in change, which makes for a total of $70 + $30 = $100. The owner has lost $100.
Technically, the owner lost $30 plus the value, V, of the $70 of goods. Since stores typically sell goods at a markup, the value may be less than $70. But in the case of a loss leader, the owner may have lost more than $70. Did you answer this riddle correctly?

Fastest Horse Riddle
The London Racetrack needs to submit its 3 fastest horses to the Kentucky Derby out of 25 horses. However, all of their information was lost and they don't know any of the horse's times. Similarly, they all look identical so they can't remember who's fastest.
They can only race 5 horses at once, so what is the fewest number of races they can conduct to find the 3 fastest horses?
They can only race 5 horses at once, so what is the fewest number of races they can conduct to find the 3 fastest horses?
Hint:
First you divide the 25 horses into 5 groups of 5. You conduct the 5 races and take all of the fastest horses in those races and have a race with them, giving you the fastest horse. Then you take the remaining 24 horses (excluding the fastest) and remove the 4th and 5th horses in the first set of 5 races (since they definitely have 3 horses faster than them), leaving you with 14 horses. Next you can remove all of the horses that were beat in the preliminary race by the horses that got 4th and 5th in the championship race, leaving you with 8 horses. Finally, you can remove the horses that remain that lost to the 3rd place horse in the final race in the preliminary race and the horse that got 3rd in the preliminary to the horse that got 2nd in the championship race, leaving you with 5 horses.
You can then run a final race where the 1st and 2nd place horses are the 2nd and 3rd fastest. Then you know the 3 fastest horses. Did you answer this riddle correctly?
YES NO
