Question

товар в магазине стоил 3700 руб. Сначала стоимость снизили на 10%, а потом повысили на 20%. Какова конечная стоимость товара?​

Answer 1

Исходная стоимость товара - 3700руб., это 100%

Найдем на сколько снизилась цена:

3700руб.=100%

х руб. =10%

3700руб./х руб.=100%/10%

х=3700руб. * 10%/100%

х=370руб., значит на 370руб. снизилась цена товара

3700руб.-370руб.=3330руб. стоил товар после снижения

Аналогично найдем на сколько повысилась цена:

3330руб.=100%

х руб. =20%

3330руб./х руб.=100%/20%

х=3330руб. * 20%/100%

х=666руб., значит на 666руб. повысилась цена товара

3330руб.+666руб.=3996руб. стоил товар после повышения

Ответ: Конечная стоимость товара - 3996руб.

Answer 2

Ответ:

3 996 руб. конечная стоимость товара

Пошаговое объяснение:

10% = 10/100 = 0,1

20% = 20/100 = 0,2

1. 3700 - 3700*0,1 = 3700 - 370 = 3 330 руб. стоимость товара после снижения цены на 10%

2. 3330 + 3330*0,2 = 3330 + 666 = 3 996 руб. стоимость товара после повышения цены на 20% - конечная стоимость товара

Answer 3

Problem Analysis

We are given that the price of a product in a store is initially 3700 rubles. The price is then reduced by 10% and subsequently increased by 20%. We need to determine the final price of the product.

Solution

To find the final price of the product, we can follow these steps:

1. Calculate the price after the initial 10% reduction. 2. Calculate the price after the 20% increase based on the reduced price.

Let's calculate the final price step by step:

1. Calculate the price after the initial 10% reduction: - The initial price of the product is 3700 rubles. - The 10% reduction can be calculated as 3700 * (10/100) = 370 rubles. - Subtracting the reduction from the initial price gives us 3700 - 370 = 3330 rubles.

2. Calculate the price after the 20% increase based on the reduced price: - The reduced price after the 10% reduction is 3330 rubles. - The 20% increase can be calculated as 3330 * (20/100) = 666 rubles. - Adding the increase to the reduced price gives us 3330 + 666 = 3996 rubles.

Therefore, the final price of the product is 3996 rubles.

Answer

The final price of the product, after a 10% reduction followed by a 20% increase, is 3996 rubles.
