Logic Puzzle: Who killed Jeff?

There were four men accused of killing Jeff. Their names were James, Jack, John, and Joe. Each man had to give three statements about what they know.

James says:

John did not kill Jeff.

I never knew Jeff.

I do not know who killed Jeff.

Jack says:

John killed Jeff.

Jeff was my best friend.

James told three lies.

John says:

I did not kill Jeff.

James was lying about knowing who killed Jeff: it was him.

Jeff was my best friend.

Joe says:

Jeff was John’s best friend.

I knew Jeff.

I don’t know who killed Jeff.

Through your investigations, you know that at least one of the men had played a part in killing Jeff, but only one actually killed him. Also, you find out that one man told no lies, one man told one lie, one man told two lies, and the other man told three lies. You do not know who told how many lies, but you are able to use reasoning to find one man of which you can find out that, through logic, is innocent. You ask the innocent man to give you a final statement. You use the number of lies he told to assume whether the next statement he gives you is true or false.

He says: James knew Jeff.

So, using logic, who killed Jeff? Who told how many lies? Which statements are the lies?

those wouldn't be real rhombuses bc of different bordering side lengths. Easy as that

Great "riddle". That's definitely one to tell your kids.

well i solved the riddle of looking it up so i'll put answer in spoiler because i'm too ashamed to take credit of it myself

Spoiler
10

the entire structure can be collapsed into just the left-most and right-most triangles; it's invariant under linear translation of the inner triangle base vertices. you end up with base 12 triangle, base 16 triangle, and the square on top of them. then use some trig

here's some work shown so i don't feel as bad

I'll give 3 stickers to whoever first gets the answer/explanation to the square problem.

They all have the same side. There is enough information.

also there is not enough information

Okay one more non-riddle. Thor was good enough for the other one.

Find the side length of the red square. There are 10 rhombuses and 5 isosceles triangles in the picture.

I'll upvote the correct answer

This is a troll problem it is easily invalidated by basic geometry. All of the rhombuses would have to have the same side length for this to be true and they don't

so you googled the problem and didn't account for the change in speed that i wrote down in my statement of it

lol

anyway here's the solution:

Spoiler
consider when two ants collide. because of the mechanics of the collision, it's the same as if the ants just walked through each other. therefore the problem is equivalent to just having each ant walk along the meter stick at a constant speed, which means the longest time that it would take is for one ant at the very end to walk to the other end, which would take 1 second using the numbers in my formulation
What if there are two ants occupying the same point (which is clearly possible given your previous answer) but starting out in the same direction?

what if ur a dyke

These aren't riddles they're science problems.

Why don't you ask the rods which is magnetic and the one that replies is fake cuz magnets can't talk

JeffreyAaronover 9 years ago

This person has a big di'ck and is black. Who is it?

Codyover 9 years ago

ok i came up with a silly ish answer and then looked it up

i was wrong but my answer was that because your blood contains iron you can put the poles close to your skin and whichever one makes your skin flushed is the one that's magnetic

it's not as clever as the real answer tho but the real answer requires some knowledge of physics

Idk man the magnet is pretty strong

you could ask Thor to use his hammer to break both rods. The magnetic one will find his other half

Oh man why is my response in the middle .. anyway I'm not reading your bloody essay again! Could just say the figure

Hit one of them many times and then see if it attracts the other rod. If it doesn't, it means the one you hit was magnetic.

Of course, destroying its magnetism sort of defeats the purpose.
