trentonlf: cut the ropes exactly in half, after you burn 3 ropes you should be at 45 minutes
When I last heard this riddle, you could not count on a constant burn rate for the ropes. You know that rope A burns for an hour, but if you were to cut it in half, one length might burn for 25 mins, and the other for 35 mins, for example.

Jmich is right, if light one of the ropes on both ends at same time will take exactly 30 minutes to burn, and if when lit both ends of firs rope only light one end of second rope. Once first rope burns all the way light the other end of second rope, will be exactly 45 minutes

The answer makes an assumption that is not stated which is that the person is able to feel the warmth of the bulbs but this may not be the case. For example, the person might be wearing thick gloves or the person might be disabled and have hooks for hands...over disabled and in a wheelchair and not able to reach the bulbs to feel them.

So it's not actually a riddle but a game of guess the unstated assumptions.

Right, because this is another so-called riddle with unstated assumption.

Yeap. Just like the so called "Einstein Riddle".

JMich: Do the LED bulbs emit heat as well? I was under the impression they didn't. Thank you.
Certainly not to the extent that incandescents do!

I just double-checked with my own lights at home. I left one set on for about 5 minutes. It's a subtle difference in temperature between bulbs, but the ones that had been on were noticeably warmer. (Less so than I'd imagined, though!) I wonder if they'd warm up more if left on for longer.

Yeah, that one was posted yesterday. It's all about elimination in that one

Yeah, I agree with JMich, too. My point was that if the rope has a constant burn rate (length/time) then it's as easy as you suggested.

You are right that is should have been stated that the ropes don't burn to exactly halfway and 30 minutes would have passed.

if you add a "you can feel warm with your hands" rule it becomes a bit too easy... don't you think? :P

JMich: Yes. Set both ropes on fire, one on both ends. Once the dual one is burned, light the other end of the other rope.
correct :)

in a completely empty room there's an hanged man

the man did it all alone

there are no windows in the room

the man is hanged with a conventional rope

there's water on the floor below the man

--

how could he hang himself?

Ungunbu: how could he hang himself?
He was standing on a block of ice, which melted (hence the water).

at night a man comes back to where he lives -- when he finds out that the light is turned off he's desperate and decides to jump out the window and kill himself

why?
