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

How Many Triangles
Hint: The number is more than 100.
Finding Circles
Hint:
17
Explanation:
You can see the center circle right?
There are 16 more circles. Probably you missed them. Just concentrate on the center circle for a moment and you will find the other 16 circles.
Thus there are a total of 17 circles in the given picture. Did you answer this riddle correctly?

Triangle Kitten Riddle
Hint:
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

Clocking Out Riddle
Hint:
The Dinner Party Riddle
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.
After this happens, you ask each person, except for yourself, how many people they shook hands with. Everybody tells you a different number.
How many people did your wife shake hands with?

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?
YES NO

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

Rope Burn Riddle
You have two ropes. Each rope takes one hour to burn. These ropes are not identical, nor are they uniform; i.e. it does not necessarily take half an hour for half the rope to burn (if you have trouble visualizing this, imagine a rope of varying thickness across its length). With only these two ropes and a way to light them, how do you measure out 45 minutes?
Hint: You can light multiple ends and/or multiple ropes at the exact same time.
Light both ends of one rope, and only one end of the other rope. This will cause the first rope to burn out in 30 minutes. When the first rope burns out, there will be 30 minutes left on the second rope. So then, light the other end of the second rope, and the rest of it will burn out in 15 minutes. 30 + 15 = 45 minutes.
