A farmer sells 100kg of mushrooms for $1 per kg. The mushrooms contain 99% moisture. A buyer makes an offer to buy these mushrooms a week later for the same price. However, a week later the mushrooms would have dried out to 98% of moisture content. How much will the farmer lose if he accepts the offer?

Currently there are 100 kg of mushrooms, of which 1 kg is substance (whatever mushrooms are made of). After a week, this same 1 kg of substance is 2% of the mushrooms. Therefore there is a total of 50 kg of mushrooms, that will be sold for $50. It's $50 less than $100, so the farmer will lose $50.

how did you get 50kg of mushrooms? i don't understand

anonymous · Answer

99% of 100 kg = 99 kg so the mushrooms start as 99 kg moisture and 1kg mushroom. As they dry they still keep their 1 kg mushroom. So when they are 98% moisture they are now 2% mushroom
