Let’s do the math

This post was last edited by guanjian88 on 2015-9-8 at 14:49. A math problem that can determine whether a person has business acumen: Miss Wang sells shoes; the cost of each shoe is 45 yuan, and she sells them for 30 yuan. When a customer comes to buy a pair of shoes, she gives them 100 yuan. Since she doesn’t have any change, she goes to a neighboring shop to exchange money for 100 yuan. Later, the neighboring shop discovered that the money was fake, and Miss Wang had to pay the neighboring shop another 100 yuan. How much money has Miss Wang lost in total? (This question isn’t easy; exactly how much has she lost?) This question has been tested on various occasions, and in half an hour only 1 person answered it correctly. This question once plagued our class, sparking arguments that lasted two hours and destroying countless brain cells – do you want to give it a try? Answer: 130 yuan

It depends on whether the fake money can be spent. Assuming the money cannot be spent: pay 100 to the vendor, give 70 back to the customer (100-30); the cost incurred is 15 (45-30), resulting in a total loss of 185. Assuming it can be spent: a loss of 15 in cost.

Although I can see the answer, I still question it. This time, let’s calculate it based on how much Miss Wang paid: the cost of the shoes is 45, and Miss Wang paid 70 yuan, for a total of 115 yuan. .

Lost 115. . 45 yuan as the cost, plus 70 yuan in change. . .

The question states that one shoe is sold at a discount of 45, so at 30 each; if a customer buys a pair, then it’s 60, right?

185=45+70+70 10 characters is way too long

It’s actually a word game. . . One pair of shoes: 90, change: 40 = 130. . . . I thought it was a math problem. . To my surprise, it was a language question. . .

One pair sold at 45, discounted to 30; a pair costs 90, resulting in a loss of 60. Plus, 70 in change – so 130 in total. Is that what the original poster meant?
