Question

По первой накладной со склада было выдано 0,7 имевшегося кирпича, а по второй - 0,4 остатка, после чего кирпича на складе осталось 5850 штук. какое количество кирпича было на складе первоначально? обьясните как бе иксов только плиз

Answer 1

Решение такое: начнём с конца. Так как по второй накладной выдали 0,4 остатка, тогда 5850 - это 0,6 этого остатка. Весь остаток это 5850 : 0,6 = 9750 кирпичей.

Аналогично 9750 - это 0,3 части всех имевшихся курпичей. Поэтому 9750 : 0,3 = 32500 кирпичей.

Calculation of Initial Brick Quantity on the Warehouse

To determine the initial quantity of bricks on the warehouse, we can use the information provided in the question. Let's break down the given information step by step:

1. From the first invoice, 0.7 of the available bricks were issued from the warehouse. 2. From the second invoice, 0.4 of the remaining bricks were issued from the warehouse. 3. After these transactions, there were 5850 bricks left on the warehouse.

To find the initial quantity of bricks, we need to work backward from the remaining quantity. Let's denote the initial quantity of bricks as 'x'.

1. From the first invoice, 0.7x bricks were issued from the warehouse. 2. After the first invoice, the remaining quantity of bricks is (1 - 0.7) * x = 0.3x. 3. From the second invoice, 0.4 * 0.3x = 0.12x bricks were issued from the warehouse. 4. After the second invoice, the remaining quantity of bricks is (1 - 0.12) * 0.3x = 0.88 * 0.3x = 0.264x. 5. According to the given information, 0.264x = 5850.

To find the value of 'x', we can solve the equation:

0.264x = 5850

Dividing both sides of the equation by 0.264:

x = 5850 / 0.264

Using a calculator, we can find that:

x ≈ 22159.09

Therefore, the initial quantity of bricks on the warehouse was approximately 22159.

Please note that the calculation is based on the information provided in the question, and the result is an approximation.
