Today's Puzzle

[Kari]

Now an easy one. As the Seven Forums is a global, non-political and non-discriminating community I have decided to publish separate puzzles for for metric and imperial systems in order not to insult anyone's feelings. The order was decided by tossing coin so the fact that the metric puzzle is told before imperial one does not represent any ideologies but is a pure coincidence.

Metric:
You need to measure exactly 8 liters of water to a bigger 9 liter container. How to do it when you only have a 5 liter and a 7 liter bowl at your disposal?

Imperial:
You need to measure exactly 8 gallons of water to a bigger 9 gallon container. How to do it when you only have a 5 gallon and a 7 gallon bowl at your disposal?

fill the 20 gallon up to the top then ,take out 5 then 7 gallons leaving 8.

 

[Kari]

fill the 20 gallon up to the top then ,take out 5 then 7 gallons leaving 8.

S***. Correct answer but too easy .

I have edited the original puzzle to make it a bit more difficult.

 

[boohbah]

no it was incredibly difficult,

 

[tom982]

Can you use the 9 litre container as well? If so:

1. Fill up the 9 litre, pour 7 litres into the 7 litre container. Leaving 2.
2. Pour the 2 into the 5 litre container
3. Repeat to get another 2 litres in the 5 litre container, totalling 4
4. Fill up the 9 litre then pour one litre out by filling up the rest of the 5 litre container

 

[boohbah]

no! cos we're on a water meter

 

[Kari]

No, you can't use the 9 liter / gallon container. You need to find a way to measure 8 liters / gallons only by using the 5 and 7 bowls.

 

[drpepper]

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

 

[drpepper]

See it again. I was editing while you were reading and posting.

 

[boohbah]

me too

 

[Kari]

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?

 

[drpepper]

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

 

[Kari]

Correct answer .

 

[Kari]

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:

20||20||20
|15|15|20|
20|15|5|10|5
|5|10|5|
5||5||10

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

 

[drpepper]

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...

:roflmao:


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?
