The potato paradox
-
You have 100 lb of "mathematical" potatoes, which are 99 percent water by weight. You let them dehydrate until they're 98 percent water. How much do they weigh now? No googling, ok.

50lbs. 1lb == 1% of 100lb, and 2% == 50lbs So as not to give the game away! (hilight to reveal)

And we have a winner. That was to quick, I was hoping for a few wrong ones to start with. :)

That's why I hid it - I remembered it from somewhere.

I dont get it. Should be 99.0001 lbs or some such.
OK, so 100ib of potatoes, 99% water. That means that 1% is not water, and that weighs 1lb. If you reduce the water content to 98%, that doesn't affect the non-water part, so 1lb of the potatoes is now 2% of the total. If 2% of the weight is 1lb, then the total weight is now 50lb. For 97% you get 33.3lb, 96% gives 25lb, and so on.

Forgive me for being thick but I cannot get my head round that. In 100lb there is 1lb of starch and 99 lbs of water (yes?). So if you lose 1% of the water, isn't that just 1lb less than before?

Ok, but than please ask it for 45.359237 kg ;P :-D
It does not solve my Problem, but it answers my question
OK - the new weight is 22.679618kg.

It's simple when you see it! :laugh: If I recall correctly, I scratched my head a fair amount the first time I saw this one.

That's more lettuce than potato. A potato will clock in at roughly 75% water (just a tad more than a human). Still a nice example where math beats intuition :thumbsup:

"To 98%" of what is the question. The original weight or the final weight. That wasnt specified. :)

That's pretty clear!

These are 'mathematical' potatoes. :) But feel free to substitute with jellyfish if you want to.

Could as well have chosen a mathematical ball of lead with 99% water-content. --edit It is misleading, since we have some "experience" with potatoes not shrinking 50% when they lay in the basement.

That's because they start out at 80% water, not 99%. And because nobody regularly checks their spuds for water content... :laugh:

I keep potatoes in a dark and cool closet. After 3 months, they may have lost "some" weight, but not the same amount as your "mathematical" potatoes. Non-mathematical potatoes do not loose water in a mathematical linear way.
