Question

Семь рубашек дороже куртки на 5%. на сколько процентов шесть рубашек дешевле куртки?

Answer 1

Пусть х руб стоит куртка, тогда 0,75 х стоят 5 рубашек 
0,75х :5=0,15 х руб. стоит 1 рубашек 
0,15х * 7 =1,05 х руб стоят 6 рубашек 
1, 05х-х=0,05х = 5% на 5% 6 рубашек стоя дороже одной куртки

Answer 2

Calculation of the Price Difference

To calculate the percentage by which six shirts are cheaper than the jacket, we need to first determine the price difference between the two items.

Given that seven shirts are more expensive than the jacket by 5%, we can assume that the price of the shirts is 105% of the jacket's price.

Let's denote the price of the jacket as J and the price of one shirt as S.

According to the given information, we have the following equation:

7S = 1.05J To find the price of one shirt, we divide both sides of the equation by 7:

S = 1.05J / 7

Now, we can calculate the price of six shirts:

6S = 6 * (1.05J / 7) = 0.9J

Therefore, six shirts are cheaper than the jacket by 10% (0.9J is 90% of J).

Answer

Six shirts are 10% cheaper than the jacket.
