A question to test your IQ

Here’s the situation: Your elder brother goes to buy vegetables from a vendor who is selling them. There are 100 pounds of scallions in total. Your brother asks how much each pound costs, and the vendor says it’s one yuan per pound. Then your brother asks how much the white part of the scallions costs per pound, and the vendor replies that it’s 0.8 yuan per pound, while the green part costs 0.2 yuan per pound. There are 50 pounds of each type. Your brother decides to buy everything, pays the vendor 0.8 yuan x 50 + 0.2 yuan x 50 = 50 yuan, and then leaves. Later, the vendor starts to think that something isn’t right – after all, 100 pounds of scallions should be worth 100 yuan, so why was only 50 yuan received? ? 0.8 yuan for the white part of the onion plus 0.2 yuan for the green part – in total, 1 yuan gets you 2 jin of onions
Each scallion is divided into a white part and a green part, so all 100 scallions have both a white part and a green part. Yes, (0.8+0.2)*100=100. But the vendor deliberately divided the amount of scallions into two parts using the white and green parts of them, which is why the seller got confused.

Reply 1# sundeili: It should be the price added together and then multiplied by the weight.
Reply to 4# A Shan: I didn’t finish elementary school, haha
Hmm... how did I not think of that? It seems I need to go back and read elementary school books again:L
Just spend some time at the Toraumi River Recreation Area and you can skip straight to high school!
Bro, I want to come more often too. It’s just… I get seasick……
Green onion whites cost 0.80 yuan per pound, while green onion greens cost 0.20 yuan per pound; with 50 pounds of each, the average price for the whole onion is 0.50 yuan per pound
