This makes no fucking sense at all. The potatoes lost 1% of their weight, so it should be 99kg.

Actually read the wiki you linked to. It explains why you're wrong, retard.

real potatoes are more like 60% water, the paradox is invalid

>> No.11968499

>>11968473
indeed, for a water percentage of 79% (quoted from the wiki) you get a water loss of 4.5 kg, so the final weight is 95.5 kg

next time, boil the potato instead of your head

If its hard to conceptualize as stated, think of the converse:
>Potatoes are 1% solid, left out for a day, they become 2% solid.
That means the ratio of solid potato weight to total potato weight must have doubled, but because we know no more solid potato was added, we know that the weight of each potato must have been halved.

>> No.11968574

Suppose the 1% solids weigh 90kg and the 99% water weigh 10kg, what now?

Potatoes are multidimensional plants. They anchor all of existence together. That's why Idaho is full of mormons.

The key is in understanding the question is asking for a reduction in CONCENTRATION of potatoes to water FROM 99% TO 98%, NOT reduction in total weight from 99% to 98%.

This is how concentrations work.
To increase the concentration of salt to water from 99% to 98% I would have to put in twice as much salt.
To Decrease the concentration of salt in my water from 99% to 98% by boiling, I would have to boil off 50% of my water.
Get it?

This is a concentration problem by weight; not a comparison of weights of potato solids to water.

Treat it as a concentration:

If I have a pot of water with salt that is 99% water and 1% salt, and I boiled off the water until it was 2% salty, I would have to boil off half the water, But the ratio of salt to water by weight would be 98% water and 2% salt.
