If we assume the change in the weight of the sack of potatoes is due solely to evaporation of water, then the answer is straightforward: the sack originally contained 99 lbs of water and 1 lb of starch. The next day, it still contains 1 lb of starch. If that constitutes 2% of the new weight, then the sack of potatoes now weighs 50 lbs.

On the other hand, the weight might have changed because a rat ate some of the potatoes. In this case, the answer is indeterminate.

Correct! Well done.

A man has a sack of potatoes which total 100 pounds. He's interested in how much water is in the potatoes, so he tests them with a potato-water-testing-machine and discovers they are 99% water and 1% starch (by weight).

He puts them on his porch overnight just to see what will happen. He's a weird, curious feller.

In the morning, he tests them again to see what percentage (by weight) the potatoes are. He discovers they dehydrated a bit and are now 98% water and 2% starch.

How much do the potatoes weigh in whole?



Since the starch never went anywhere, the amount of water must have reduced to 49 pounds for the potatoes to be 98% water after the evaporation. So, 1 pound starch + 49 pounds water = 50 pounds after the evaporation.

I've probably told this one before, but it bears repeating.

Axelwolf, djatc, and RS walk into a motel and inquire about the price for one night. The clerk says $30. They each fish a $10 bill out of their pockets and each pays his share.

An hour later, the manager realizes they were supposed to be running a $25 promotion. He calls over the bellman and gives him five $1 bills and says, please return it to those guys from Vegas, because they overpaid.

On the way to their room, the bellman recalls those cheap guys never tipped after he helped with their luggage and that they would probably get into a cat fight about how to divided up five one dollar bills between three people. So he quietly keeps $2 for himself and returns $1 to each of three them.

So, each man ended up paying $9 for the room and the bellman got $2. 3*$9 + $2 = $29. But, they originally paid $30. Where is the missing dollar?

Please put answers in spoiler tags.

If anyone would split a $30 hotel room it would definitely be those three

Fake News. They would never miss a promotion like that

There are five main characters -- AW, DJ, RS, Bellman, and the hotel -- at no point in their transactions has money been destroyed
1: AW, DJ, RS, each pay $10, hotel receives $30. AW -10, DJ -10, RS -10, hotel +30. Add them all up and it equal zero
2: AW -10, DJ -10, RS -10, bellhop +5, hotel +25. Add them all up and it equals zero
3: AW -9, DJ -9, RS -9, below +2, hotel +25. Add them all up and it equal zero.

The error is adding +2 to -27 is -25, not 29


I should also be able to use basic algebra to show that the results of woman = evil is wrong. Maybe tonight.

Each of the three guys paid $9 for their room, a total of $27. The $27 went: $25 to the hotel and $2 to the bellman.

You cannot add the $2 bellman "tip" to the $27 because the $2 bellman "tip" was a part of the $27 that the the three guys paid.

The best you can hope for is to show that "woman = evil" is an overstatement, it should be "woman = moody."
