Answer
Math Puzzle 1
Try to find the connection
between these equations.
If you can solve this Puzzle,
you are a Math Wizard!
It's actually quite simple: every
number after the equals sign
actually represents the results of
three sums formed by multiplying,
adding, and subtracting the two
numbers before the equals sign.
For example, 8 + 2 = 16106
8 x 2 = 16
8 + 2 = 10
8 - 2 = 6
The same principle applies to all
the equations after this.

requires a password he doesn't know. So, he waits

As a club member comes to the door, the security
officer says, "Twelve". She replies, "Six" and gets

Another member comes to the door. The security

gets in.
Matt thinks that he understands the pattern and
walks up to the door. The security officer says,
"Ten" and Matt replies, "Five" but the security
guard doesn't let him in.
Question:
What's the password? Explain
Matt was supposed to say the
number of letters in the word told
to him by the security guard. The
word "twelve" has six letters, the
word "six" has three. "Ten" has
three letters, so the password
would have been "Three".

Answer
4 criminals are lined up on some steps. They are all facing in the same direction. A wall
separates the fourth man from the other three. So to summarize:
Man 1 can see men 2 and 3.
Man 2 can see man 3.
Man 3 can see none of the others.
Man 4 can see none of the others.
The criminals are wearing hats. They are told that there are two white hats and two black
hats. The men initially don't know what color hat they are wearing. They are told to shout
out the color of the hat that they are wearing as soon as they know for certain what color
it is.
They are not allowed to turn round or move.
They are not allowed to talk to each other.
They are not allowed to take their hats off.
Who is the first person to shout out and why?

They are not allowed to turn round or move.
They are not allowed to talk to each other.
They are not allowed to take their hats off.
Who is the first person to shout out and why?
Answer
Man 2 will shout out after
some time.
Here's why :
Man 3 and 4 cannot see
the others’ hats.
Man 1 sees a white hat
and a black hat and
knows his hat can be
black or white.
Man 2 sees one black
hat , but if he is also
wearing a black hat, it
would be obvious to Man
1 that he is wearing a
white hat. Since Man 1
did not shout out, Man 2
concluded that he
himself is wearing a
white hat.
