This is a mathematical inequality used in practical problems. Suppose that the number of oranges purchased by the merchant is Y and the price is X. If the purchase price is known as 1 yuan, the cost price is Y yuan. Because there is a loss of 5%, the actual number of oranges that can be sold is 95%y, so the total amount actually sold is.

95%xy, if you don't lose money, 95%xy is greater than or equal to Y, and X is not less than1.052615789473684210526315789474, so the merchants set the price at least at this figure. This number is really confusing. The person who caused this problem deliberately fooled others. )
