The worlds first riddle!

AGES
Eilah is 6, Sally is 9

1/2 OF 16
There is no base where 1/2 of 16 is 13. Therefore, I'll assume that there are two bases involved and that one of them is ten.

If 16 is base 10, then 13 must be base 5. If 32 is base 10, then the base 5 representation of 32/3 (base 10) is 20.31...

If 13 is base 10, then 16 must be base 20. If 32 is base 20, then the base 10 representation of 32/3 (base 20) is 20.66...

100

(0*1*3*6*7*8*9)+(4*5^2)
(0*1*3*6*7*8*9)+(4*5/.2)

I must say every day,' I must do better'.

There are several ways, but here are two:
97 30/45 + 2 6/18; 89 + 6 1/2 + 4 35/70

1/3 If you set it up as a proportion, it's easier to see:
1/2 (16) = 1/3 (32)
13 x
Cross multiplying gives:
8x = 416/3
x = 416/24
x = 17 1/3

Eilah is 6, and Sally is 9.


You have a huge box of beautiful decorated tiles, enough to provide a border in two rooms. You really can't figure out how to arrange them, however. If you set a border of two tiles all around, there's one left over; if you set three tiles all around, or four, or five, or six, there's still one tile left over. Finally; you try a block of seven tiles for each corner, and you come out even. What is the smallest number of tiles you could have to get this result

A car company sold 150 cars in a special 6-day tent sale offer. Each day the company sold 6 more cars than the day before. How many cars were sold on the 6th day

When the two met, one was half the other's age plus seven years. Ten years later, when they married, the bride was thirty, but this time one was nine-tenths the age of the other. How old was the groom
( no fractions, no partial years---whole numbers only.)

CARS
40

AGES
27

TILES
This doesn't make sense to me. If only one tile is left over when the border is two, won't you run out of tiles when the border is more? Or does a border of two mean every other tile, and a border of 3 mean every third tile, etc?

If I can not make myself clear, please do not waste your time.

There are 301 tiles. This is the smallest number that will give you a remainder of 1 when divided by 2, 3, 4, 5, and 6, but divided by 7 leaves no remainder.

On the first day, the company sold x cars. On the second day, x + 6, on the third day, x + 12, on the fourth day, x + 18, on the fifth day, x + 24, and on the sixth day, x + 30.
If you add all the days together you get the equation:

x + (x + 6) + (x + 12) + (x + 18) + (x + 24) + (x + 30) = 150 cars sold
6x + 90 = 150 and so x = 10. Therefore, on day 6 (x + 30) = 40

The bride was 30; the groom was 27.


The gentlemen Dutch, English, Painter, and Writer are all teachers at the same secondary school. Each teacher teaches two different subjects. Furthermore:

• Three teachers teach the Dutch language
• There is only one math teacher
• There are two teachers for chemistry
• Two teachers, Simon and Mr English, teach history
• Peter doesn't teach the Dutch language
• Steven is a chemistry teacher
• Mr Dutch does not teach any course that is taught by Karl or Mr Painter.

The Question: What is the full name of each teacher and which two subjects does each one teach

TEACHERS
Peter Dutch (Math, Chemistry)
Karl English (Dutch, History)
Simon Painter (Dutch, History)
Steven Writer (Dutch, Chemistry)

HANDSHAKES
4 choose 2 = 6

Six it is. I don't know why I got that one wrong.


Here's one for the math wizards: Three companies agree to split the $1,000,000 cost associated with a toxic waste cleanup, as follows:

1) Company A agrees to pay four times the amount of Company B;

2) Company C agrees to pay one-fourth the sum of the amounts paid by
Companies A and B.

How much will each company pay


We are five little things of a similar sort. You will find us all on 'a tennis court'.

What are we


"One third of six and two thirds of eleven can make seven."

Please explain why this statement is correct.

TOXIC WASTE
A pays $640K
B pays $160K
C pays $200K

TENNIS COURT
The vowels.

SEVEN
S (one third of 'six') and EVEN (two thirds of 'eleven') make SEVEN.

Well Mark, it appears it is just you and me, and I am at a severe disadvantage due to your terrific answer rate.

TOXIC WASTE
A pays $640K
B pays $160K
C pays $200K

Answer: Let x, y, and z be the amounts paid by Companies A, B, and C respectively. Since the total cost is $1,000,000, we know that x+y+z=1,000,000. From the other two conditions, we have x=4y and z=(x+y)/4 or equivalently, 4z=x+y. Substituting 4z for x+y into the first equation gives 4z+z=1,000,000, 5z=1,000,000 and z=200,000. Of the remaining 800,000 (x+y=800,000), substituting x=4y for x gives 5y=800,000, or y=160,000. Finally x=4y or $640,000.

SEVEN
S (one third of 'six') and EVEN (two thirds of 'eleven') make SEVEN.


Time to up the ante.

Say that a man has two cubes on his desk. Every day he arranges both cubes so that the front faces show the current day of the month. What numbers are on the faces of the cubes to allow this practice to occur

A guy bet his neighbour $100 dollars that his dog could jump higher than a house. Thinking this not possible, the neighbour took the bet and lost.

Why did he lose the bet


A pregnant lady named her children: Dominique, Regis, Michelle, Fawn, Sophie and Lara. What will she name her next child?

Jessica, Katie, Abby or Tilly

Yeah, where'd everybody go? How'd your SP2 update go? If/when PMs come back, is that how I should reply? I noticed that at times that seemed to be the protocol.

CUBES
0,1,2,3,4,5
0,1,2,6,7,8 (the six does double duty as a nine)

DOG
Houses can't jump.

PREGNANT
Just when I was about to give up, Julie Andrews started singing in my ear: Tilly

Mark, SP2- sweet. Although I can't say I have noticed any difference though. I dont know much about it. For much, read nothing.

As for PMs, don't bother. If you have an answer just post it up. Very few can answer these questions, and they only get more difficult from here on.

A psychologist goes to a village in Africa and decides to compare foot size to intelligence. He notes that in general, as foot size increases, so does intelligence.

How can this be


A puppy is one, but a dog is not.
A kitten is one, but a cat is not.
A cookie is one, but a cracker is not.

What is it


This is a true story from Taiwan.

A rich man's son was kidnapped. The ransom note told him to bring a valuable diamond to a phone booth in the middle of a public park. Plainclothes police officers surrounded the park, intending to follow the criminal or his messenger. The rich man arrived at the phone booth and followed instructions but the police were powerless to prevent the diamond from leaving the park and reaching the crafty villain.

What was the man instructed to do


A train just leaves a station and enters a tunnel. Where is the best place for a claustrophobic person to sit so they are in the tunnel the shortest time

Train:
At the rear. The train will accellerate, so the rear part of the train will be in the tunnel the lease amount of time.

FOOT SIZE
Intelligence increases with age through the growing years. People with very small feet are very young. People with larger feet are probably adults.

Foot Size
It is a poor researcher (or poor test) that does not account for age variations.
Also, IQ peaks (if my recollection is correct) in the late 20s. After that, experience offsets the loss of raw intelligence.

Quibbles only. I expect that your answer is the expected on.e
