Question

После повышения цен на 10% костюм стал стоить 2750 руб. сколько рублей стоил этот костюм до повышения цен? на сколько рублей увеличилась его цена?

Answer 1

2750-110%
х-100%
110х=275000
х=2500 (руб)- стоил костюм до повышения цены
2750-2500=250(руб)- увеличилась цена

Answer 2

100%+10%=110%
2750 руб :110 = 25 руб (1%)
25 руб * 100% = 2500 руб (стоил костюм до повышения)
2750 руб - 2500 руб = 250 руб (на столько повысилась цена)
Ответ: костюм стоил до повышения цены 2500 руб. Цена увеличилась на 250 руб

Answer 3

Calculation of the Original Price and Price Increase

To calculate the original price of the suit before the price increase, we can use the information provided. We know that after the price increase of 10%, the suit costs 2750 rubles. We need to find the original price before the increase and the amount by which the price increased.

Let's denote the original price as x.

The price after the increase can be calculated using the formula:

Price after increase = Original price + (Original price * Percentage increase)

In this case, the price after the increase is 2750 rubles, and the percentage increase is 10%. Substituting these values into the formula, we get:

2750 = x + (x * 0.1)

Simplifying the equation, we have:

2750 = 1.1x

To find the value of x, we can divide both sides of the equation by 1.1:

x = 2750 / 1.1

Calculating this, we find that the original price of the suit before the price increase was approximately 2500 rubles.

To determine the amount by which the price increased, we can subtract the original price from the price after the increase:

Price increase = Price after increase - Original price

Price increase = 2750 - 2500

The price of the suit increased by 250 rubles.

Therefore, the suit originally cost 2500 rubles, and its price increased by 250 rubles.
