Challenge: Divide fourteen sugar cubes into three cups of coffee so that each cup has an odd number of sugar cubes in it.

Haha! That's thinking outside the box, I like it!

Not the answer I was given though. ;)

Zero's kind of an odd number, isn't it?

Divide 7 cubes into smaller cubes - 1 horizontal and 1 vertical cut gives 7x8=56 little cubes and 7 big cubes. 63/3=21/cup, but there are many other solutions.

Spoiler:
It's not possible to solve this using only the standard mathematical definitions of the terms, therefore the answer to this riddle is based on an equivocation of one of the terms, most likely the word "odd". And by "odd" you probably mean "weird" or "strange" or "unusual". Since 12 is an unusual number of sugar cubes to put in a cup of coffee, the answer is 1, 1, and 12.

Interesting. And yes, there are many other solutions. That's what I like about these "tricky" ones; you get a lot of interesting solutions.

Correct! And by "correct" I mean you got it word for word, which makes me suspect Googling! :shakefist:

I prefer thinking outside the box. tehe...
It's fun thinking up different solutions
thanx for posting it. :)

Hey if 12 is an odd # because 1+2=3
then there is another answer, 1/3/10.

I knew it must have been something like that when I said zero is kind of an odd number.

If a red train with 50 passengers leaves Los Angeles at 5 pm, heading west at 100 mph and a blue train carrying 75 passengers leaves Boston at 4:45 pm, heading east at 120 mph., why should it matter how much %$#@# sugar I put in my $#%@ coffee?

Because when you use too much sugar
you will get there before the train.
Then you get impatient waiting. lol

But looks where I am now...!

What I want to know is how long does it take the two trains to end up in the ocean...?

1. Place 7 cubes in cup 1.
2. Place 5 cubes in cup 2.
3. Place 1 cube in cup 3.
4. Drink coffee in cup 3.
5. Place 1 cube in cup 3.

Aha! But then it's not a 'cup of coffee'! And you can't have sugar 'cubes' in coffee, because they dissolve.

Mug 1: Two cubes
Mug 2: Five cubes
Mug 3: Seven cubes

All mugs hold a prime number of cubes. Prime numbers are strange. Strange is a synonym for odd.

Wow. I just saw my mistake. I didn't realize what I typed until now. I apologize for the error.

The correct question is: If a BLUE train with 50 passengers leaves Los Angeles at 5 pm, heading west at 100 mph and a RED train carrying 75 passengers leaves Boston at 4:45 pm, heading east at 120 mph...

I regret any inconvenience I may have caused.

In the second clause, "cube" describes a quantity of sugar, not a shape.

Or the third cup has an odd number of cubes before its cube melts and I drink the coffee, and it also has an odd number of cubes, so It comes down to the meaning that "has" has.
