Answer:
Consider all factorizations of 2450 into integers a, b, c. (Since
these three variables represent ages, all factors above 98 should
be excluded!) The remaining triples (a,b,c) sum to distinct values
_except_ 50+7+7 = 49+10+5 = 64. Since the assistant did not have
enough information at this point, one of these two triples must be the
correct answer; in particular, the secretary's age is 64/2 = 32.
If the professor is 49 years old or younger, her assertion about
being older than all others at dinner cannot be true; if she is 51
or older, that information would not help the assistant. Hence,
the professor is 50, and her dinner guests had ages 49, 10, 5.
An old king is about to die and he has no offspring to inherit the crown. So he summons the three wisest men from his kingdom and puts them to a test. He tells them that he is about to put them in a room and have his aide put a hat on each of them. Each hat may or may not have a dot on it, but at least one hat will have a dot. They may not touch the hats, nor communicate in any way. The first one that correctly identifies whether his hat has a dot will become the next king. If he is wrong, or if he breaks the rules, he will be killed. Then he sends all three wise men into the room.
The king then tells his aide to put dotted hats on all three.
A few minutes later one of the wise men returns and announces proudly that he has a dot. How did he know?
The wise man saw the dot when the aide put the hat on his head.
There was a pee puddle in the other room, that he saw his reflection on
He asked to put the hat on his hand? (it doesnt specify that the hat is on the head)
the wise man just asked the aide
Cannot communicate...
didn't he just see the reaction of the other wise men and, seeing as poker wasn't the national sport back then, concluded he had a dotted hat
he was the first guy willing to bet his life on a 50/50 chance

ya gotta know TBO
ya gotta know when to hold em
know when to fold em
know when to walk away
know when to run
well can it be that he figured, cause he was a wise man, that none of the others went outside. Cause they weren't sure if they had a dot, but they knew at least one of them should have a dot. He deducted he must have also have a dot.

Answer:
Person A saw that B and C both had dots. A put himself in B's
situation. Assuming A did not have a dot, then B would see one dot on C
and none on A. Person B would then think, "if I had no dot, then C would
see no dots and know that C had the only dot, and C would be able to answer
immediately. However, since C does not answer, I must have a dot."
However, A sees that B doesn't answer, which means A must also have a dot,
so A goes to the king and declares victory.

if you read the question, it does say..... 3 dots placed and any amount of dots possible
so its 3 not 2
it doesn't really matter does it tbo. The point the yell makes is that, those guys went in not knowing if they had a dot or not. So 50/50 chance of having a dot, has nothing to do with the others. Only if the riddle would say one and only one dot. The Yell is right.
Does this mean anything:
"Now, I know a magic utterance to assist maths"

if this is the one thats too hard, ive heard it before 
just count the number of letters in each word 
I think the magic utterance part throws peeps off tho
Alundra is correct, but do you know what the numbers mean?
= pi!!

yup But I'm playing nice, if Ive heard one before i wont answer
also the answer to your other one is sentence is spelt wrong. and thats the only mistake, so technically the sentence is a lie, making it 2 mistakes
