The Number Of Triangles
Hint:
Prince Age Riddle
A princess is as old as the prince will be when the princess is twice the age that the prince was when the princess's age was half the sum of their present ages.
What are their ages?
What are their ages?
Hint:
Current Future Past
Princess x 2z (x+y)/2
Prince y x z
I then created three equations, since the difference in their age will always be the same.
d = the difference in ages
x y = d
2z x = d
x/2 + y/2 z = d
I then created a matrix and solved it using row reduction.
x y z
1 -1 0 d
-1 0 2 d
.5 .5 -1 d
It reduced to:
x y z
1 0 0 4d
0 1 0 3d
0 0 1 5d/2
This means that you can pick any difference you want (an even one presumably because you want integer ages).

An Island That Has 3 Gods
There is an Island that has 3 gods. One god always tells a lie, and the other always tells the truth. The third god has a random behavior. To top it off, these three gods, being jerks, answer in their own languages such that you are unable to tell which word, between "ja" or "da", means "no" or "yes". You have 3 questions to work out the True god, the false god, and the Random god.
Hint:
Question 1: (To any of the three gods) If I were to ask you "Is that the random god," would your answer be "ja?" (This questions, no matter the answer, will enable you to tell which god is not random i.e. the god who is either False or True)
Question 2: (To either the True or False god) If I asked you "are you false," would your answer be "ja?"
Question 3: (To the same god you asked the second question) If I asked you "whether the first god I spoke to is random," would your answer be "ja?" Did you answer this riddle correctly?
YES NO
Question 2: (To either the True or False god) If I asked you "are you false," would your answer be "ja?"
Question 3: (To the same god you asked the second question) If I asked you "whether the first god I spoke to is random," would your answer be "ja?" Did you answer this riddle correctly?

Age Of Three Daughters Riddles
I was visiting a friend one evening and remembered that he had three daughters. I asked him how old they were. The product of their ages is 72, he answered. Quizzically, I asked, Is there anything else you can tell me? Yes, he replied, the sum of their ages is equal to the number of my house. I stepped outside to see what the house number was. Upon returning inside, I said to my host, Im sorry, but I still cant figure out their ages. He responded apologetically, Im sorry, I forgot to mention that my oldest daughter likes strawberry shortcake. With this information, I was able to determine all three of their ages. How old is each daughter?
Hint:
3, 3, and 8. The only groups of 3 factors of 72 to have non-unique sums are 2 6 6 and 3 3 8 (with a sum of 14). The rest have unique sums:
2 + 2 + 18 = 22
2 + 3 + 12 = 18
2 + 4 + 9 = 15
3 + 4 + 6 = 13
The house number alone would have identified any of these groups. Since more information was required, we know the sum left the answer unknown. The presence of a single oldest child eliminates 2 6 6, leaving 3 3 8 as the only possible answer. Did you answer this riddle correctly?

Prisoners Were Told That They Have A Chance To Be Free Riddle

The prisoners can talk to only ONE guard, and ask only ONE question. Which question should they ask to find the door that will take them to freedom?
The prisoners can talk to only ONE guard, and ask only ONE question. Which question should they ask to find the door that will take them to freedom?
Hint:
They should ask any guard "is the freedom door next to the lying guard?" If the guard answers "yes" they should go to the other door. if it was the liar, the other door takes them to freedom. If it was the honest guard, the other door is also what the prisoners want. If the guard answers "no" they should go to the door next to him: if it was the liar, the door next to him takes them to freedom. If it was the honest guard, the door next to him is also the right choice. Did you answer this riddle correctly?

Two Zero And Two Four Riddle
Hint:
B) 2024
When you pronounce a number say, 3006, it is pronounced as three thousand six. But, it is not pronounced as three two zero and six. Because, it will result in 3206. It might be grammatically but mathematically wrong or vice versa.
The pronunciation does not say how many but what the number is at the particular position.
Hence, 2024 has two zero and two four. Did you answer this riddle correctly?

I Enter The Garden There Are 34 People Riddle
I enter the garden. There are 34 people in the backyard. You kill 34 people. How many people are in the garden?
Hint:
If the backyard and garden are two different locations then there would be one person left in the garden. This is because the murderous rampage took place in the backyard, not the garden. However, the riddle solver considers that the backyard and the garden is the same place then, then zero people would be left, as the killer would technically be counted amongst the 34 people.
