Ok, here's a nice one...

A mother is 21 years older than her daughter.
In 6 years, this mother will be 5 times as old as her daughter

The question is: Where is the dad???

Intermezzo:
Some people get confused and will start asking WHO the dad is.
I don't know the question to that answer either. Only the mother can be 100% sure on that.
And no math can answer that questiong.

Some people may be confused by the sudden "appearance" of the dad and because of that, forget about the math.
Still, the question can be answered by simple math...

(scroll down for the solution)

































Set the mother's age to X
Set the daughter's age to Y

"The mother is 21 years older than her daughter" will then give this equation:
X = Y + 21

and "in 6 years, the mother will be 5 times as old as her daughter" will make:
X + 6 = 5(Y + 6)

We now have 2 equations with 2 unknowns, so we should be able to solve it:

In the second equation, substitute the value of X (= Y+21).
This will give:

Y + 21 + 6 = 5(Y + 6)
=>
Y + 27 = 5Y + 30
=>
Y - 5Y = 30 - 27
=>
-4Y = 3
=>
4Y = -3
=>
Y = 0.75

And there's the answer...!

The daughther is at this moment -0.75 years old, or -9 months
So the dad is on top of the mother right know (IMG:http://www.914world.com/bbs2/html/emoticons/cool_shades.gif)

You're all wrong...if the child is 9 months old, the dad was there 18 months ago and has long since disappeared.

Old mathimeticians never die, they just lose some of their functions..... (IMG:http://www.914world.com/bbs2/html/emoticons/rolleyes.gif)


Three men were on a business trip and had to stay in a hotel
over night. The price of the room was $30.00, so the men
decided to split one room, three ways. Each one paid $10.00.
Well after they paid, the manager realized that he overcharged
them on their room. The room only cost $25.00, so he gave the
bellboy five one dollar bills to give to the three men. On his
way up to the room the bell boy was trying to think of a way to
split $5.00 three ways. After thinking about it awhile, he decided
to keep $2.00 for himself and give each man $1.00 back. Now, if
each man (who paid $10) gets $1 back that means they each paid
$9.00 ($10 - $1 = $9 ). $9.00 multiplied by 3 (because there are
three men) equals $27.00 plus the $2.00 the bell boy kept equals
$29.00! What happened to the missing dollar?????

The answer was -9.. but that still isn't quite right as the 9 months starts at the end of the mom's last period.. not necessarily at conception. (strange, eh?)

You're forgetting the most important thing. Is she hot? If she isnt hot, age doesnt really matter... If she is hot you just have to make sure she's over 18 (IMG:http://www.914world.com/bbs2/html/emoticons/smile.gif)

She doesn' t have to be over 18, she just has to say she's over 18 (IMG:http://www.914world.com/bbs2/html/emoticons/cool.gif)

I've got some good comments like above, but I am sure everyone has heard them all, and if someone has a daughter might get kinda mad. Or call me a sick bastard or something to that extent.

How do you know it's a girl?

Actually, the father just finished flushing the broken condom down the toilet and is getting dressed so he can head home, and avoid having to "cuddle"

Trick question for one of two reasons:

a. Hotels wouldn't really refund a measly 5 bucks.

or

b. The bellboy would keep all 5 dollars.

I'll throw out a hint. There is only one word wrong in the puzzle. (I'm talking about the hotel puzzle) It's in the second to last line.

hey, that's a funny one!

it's just a confusioning presentation however... 9*3=27 which is $2 more than they should have paid -- that $2 being in the bellboy's pocket. keep things linear and it works out.
