As a follow up to Sn0rts post: http://www.blackhatworld.com/blackhat-seo/blackhat-lounge/591138-wheres-missing-dollar.html

Here is my riddle:
I got this riddle when I first went to work for Microsoft as a developer...

---------------------------------------------------

You have regular "weighing scale"... (not a libra scale)

you receive 3 pots of pills.

In each pot there are 100 pills

each pill weighs 10 grams

1 pot has poisened pills, these pills weigh 9 grams a pill

you can only weigh 1 time...

How do you find the poisened pills ?

the poisened pills are an exception. 1 pot has poisened pills. they weigh 9 grams each

regular pills weigh 10 grams

poisened pills and regular pills look exactly the same.

You take 10 pills of the first pot, 6 from the second, and 1 from the last, and you weight the 17 pills at the same time:
-If the weight is 160g, then the 10 pills are poisoned.
-If the weight is 164g, then the 6 pills are poisoned.
-If the weight is 169g, then the 1 pill are poisoned.

So do we not have to determine the poisoned ones after weighing? Like are we allowed to mix? Because else, it seems impossible.

Now eat your junkfood or take the pills by random for dying slowly or fast, respectively.

Is one pot filled just with poisoned pills or there is a random number of pills?

So, where is the riddle? This is so easy that I won't even bother giving the answer....I thought there are just a couple of bad pills

Edit: Just saw a guy gave the answer already, what a stupid "riddle". So, that's what you gotta answer to enter Microsoft...good Lord, Bill Gates went crazy

All of the pills would be poisoned due to cross contamination
