Answer 1

Ответ: 16 процентов

Answer 2

Надеюсь правильно
(30% * х - 30% *40% * х) + (70% * х + 70% * 40% * х) = 0,18х + 0,98х = 1,16х
1,16х - х (первоначальная цена) = 0,16х
Ответ: 16%

Answer 3

Problem Analysis

We are given that a person bought clothes from a seller for X rubles. Then, the person sold 30% of the clothes for 40% less than X, and 70% of the clothes for 40% more than X. We need to find the profit made by the person as a percentage.

Solution

Let's break down the problem step by step:

1. The person bought clothes from the seller for X rubles. 2. The person sold 30% of the clothes for 40% less than X. This means the selling price for 30% of the clothes is 60% of X. 3. The person sold 70% of the clothes for 40% more than X. This means the selling price for 70% of the clothes is 140% of X.

To find the profit, we need to calculate the total cost and total selling price of the clothes.

Let's assume the cost price of the clothes is C.

1. The cost price of the clothes is X rubles. 2. The selling price of 30% of the clothes is 60% of X, which is 0.6X. 3. The selling price of 70% of the clothes is 140% of X, which is 1.4X.

The total cost price of the clothes is C = X.

The total selling price of the clothes is: S = (0.6X * 30%) + (1.4X * 70%) = 0.18X + 0.98X = 1.16X

The profit made by the person is the difference between the total selling price and the total cost price: Profit = S - C = 1.16X - X = 0.16X

To find the profit as a percentage, we divide the profit by the cost price and multiply by 100: Profit Percentage = (Profit / C) * 100 = (0.16X / X) * 100 = 16%

Therefore, the profit made by the person is 16%.

Answer

The profit made by the person is 16%.
