A man went to the market to sell green onions. 1 Jin Yuan. Total 100G. A customer came soon. The customer asked how much the green onions cost. The onion seller thought about it. verdant

Actually, the onion seller marked the price wrong.

Because, when the original 1 yuan a catty of onion is sold separately, it should be priced according to the ratio of a catty of onion to onion, so that the selling price can be the same.

Example: If 1 yuan 1 kg of onion accounts for 5% of onion, and onion accounts for 5% of onion, then onion is 0. 5 Jin 0.5 yuan is right, and so is the green one.

That is to say, onion 1 kg is 1 yuan, and so is onion.

He priced the scallion at 7 wool 1 kg, and the scallion at 3 wool 1 kg, which was equivalent to only 2 kg 1 yuan. The result is 50 jins of onion +50 jins of onion as long as 50 yuan.
