1. fill 7 liter ( or gallon)
2. pour remaining contents of 7 liter (or gallon) into 9 liter (or gallon)
3. empty 5 liter (or gallon)
4. repeat #1 #2, and #3 three times

Doesn't make sense? Would you please review your answer?

Well Phooey!!! ...editing error... I'll do it in sentence structure instead.

Perform the following operations four times.

Fill the seven liter/gallon container from the tap. Fill the five liter/gallon from the seven liter/gallon container. Pour the remaining contents of the seven liter/gallon container into the nine liter/gallon container. Empty the five liter/gallon container.

math:
7 - 5 = 2
four times ---> 4 * 2 = 8

Correct answer :).

Here's the next one:

See the image below. It has 5 times number 20, 3 times number 15, 3 times number 10 and 6 times number 5. Now change the order of these numbers so that all 4 lines (horizontal, vertical, both diagonals) gives a sum of 55.

Let's see if I can just type this out:


No code has to be inserted here.

Correct, Tom. Mods: is it possible to ban Tom from this thread?

vertical,top to bottom: 15,10,5,20,5
horizontal, left to right:20,20,5,5,5
diagonal, top left to bottom right:20,15,5,10,5
diagonal , bottom left to top right:20,10,5,15,5

Phooey again! ...correct answer posted while I was figuringout how to type solution...

I'll meet you in the middle and hide my future solutions (if you're puzzles are still easy and I can do them ) so that I'm not ruining it for others and iff people look at this thread then they can still do the puzzle :)

Trying to find a puzzle Tom can't solve in two minutes I came up with this:

We have 20 matchsticks forming a 4 matchsticks by 5 matchsticks square something like this:

(Sorry, I am not a good photographer.)

Move 4 matchsticks to keep the square form so that each row and column has 5 matchsticks. A hint: try an unorthodox solution!

You've lost me. We have 20 matchsticks and you want us to form a 5x5 square?


Is it against the rules to take a row off the top and put it on the bottom?
