1. You have two old-fashioned hourglasses. One contains five hours of sand, one contains eight. How would you go about timing eleven hours?

2. You have an old-fashioned pair of scales. Given that you must weigh a series of objects with integer masses between 1 and 40 grams, inclusive, what is the lowest number of weights needed to weigh any given object?

1) turn both over. when the five runs out, turn it over, once the 8 is empty, the 5 is divided into 3:2. place the 5 on its side to suspend it, run the eight fully, then use the 3 from the 5 hourglass as it finishes. 8+3=11

2)6: 1,2,4,8,16,32

You're correct on the first one, though there's a better way of doing it, where you don't have to waste time at the start, and wrong on the second one.

For the first one, run both of them, and when the five runs out, turn it over, then when the eight runs out, turn the five over again.

1. You start timing them both at the same time. When the five-hour timer ends and the sand runs out, you know that there are three hours left on the eight-hour timer. You then simply measure the eleven hours from that point, flipping the eight-hour timer when it finishes.

To put it another way, 8-5=3. So there are 3 hours left on the 8-hour timer. Then you simply measure 8+3 which equals 11.

2. Can't be bothered to work this out as I don't have the time, however I could do if given time as I study maths. Ah well, someone else is bound to post it anyway...

i think its safe to say my riddle has been solved!!

i lost my hat this morning. after about an hour of searching, i found it. what was the first thing i did once i found it?

What happens when an unstopable force meets an immovable object?

Both things cannot exist as they contradict each other.

wrong on the second one. hmmmm...
you've got me there, what is it?

You can do it with 4: 1, 3, 9 and 27.

You can place weights on either side of a set of scales. So to measure, say, 5, you'd put a 9 on one side and a 3 and a 1 on the other.

Yes, yes paradox and all that, but superman solved it. I'm serious, there's a superman-comic where he gives the best answer to the riddle I have ever heared.

A man leaps off of the roof of an eleven story building. He takes a running start and when he leaves the roof, he is traveling at 3.2m/s.

How long does it take him to reach the ground?

The rest of his life.

DING DING!

We gave that to my Physics teacher in high school. He took the whole hour and a half of class writing it out. Bell rang, we told him the answer. Free day of class!

that isn't a specific length of time.

EDIT: specific length of time with a known magnitude.

It doesn't ask for that. Just asks how long.

What's the thing that Always goes up but never down?

the amount of time (in arbitrary units of time) which has elapsed since event x

What happens when an unstopable force meets an immovable object?

the resulting collision causes a black hole, which sucks in the unstoppable force, but cannot (obviously) move the immovable object. ergo the immoveable object wins.

very humourous, but even assuming i found it on my head, still incorrect.

One reply I've heard is just that the unstoppable force stops and the immovable object moves...

2 fathers and 2 sons were out hunting one day. By the end of the day, they had each shot and killed one duck, but they only bring home 3 ducks. How is this possible?

oh, i never even condsidered using both sides! dammit! =[

It could be but No the answer is a lot more simple

which one of you is lying?

OT: 2 fathers and 2 sons were out hunting one day. By the end of the day, they had each shot and killed one duck, but they only bring home 3 ducks. How is this possible?

It's a grandfather, a father, and a son.
