Question

Стоимость костюма была 10 д.е. Сначала эту цену повысили на 20%, а потом снизили на 10%. Какой стала цена костюма после этих изменений? На сколько процентов изменилась начальная цена?

Answer 1

10 д.е - 100%
? д.е - 120%
Повысили: ? д.е=10*120/100=12 д.е

12 д.е - 100%
? д.е - 90%
Снизили: ?д.е = 12*90/100=10,8 д.е

Если сначала 10 д.е, а потом 10,8 д.е:
10 д.е - 100%
10,8 д.е - ?%
Снизилась на:
?%=10,8*100/10=108

Значит, цена снизилась на:
108-100=8%

Calculation of the New Price of the Suit

To calculate the new price of the suit after the price increase and decrease, we can follow these steps:

1. Start with the initial price of the suit, which is 10 d.e. 2. Increase the price by 20%. 3. Decrease the increased price by 10%.

Let's calculate the new price step by step:

1. Increase the initial price of the suit by 20%: - 10 d.e. + (20% of 10 d.e.) = 10 d.e. + 2 d.e. = 12 d.e.

2. Decrease the increased price by 10%: - 12 d.e. - (10% of 12 d.e.) = 12 d.e. - 1.2 d.e. = 10.8 d.e.

Therefore, the new price of the suit after the price changes is 10.8 d.e..

Percentage Change in the Initial Price

To calculate the percentage change in the initial price, we can use the following formula:

Percentage Change = ((New Price - Initial Price) / Initial Price) * 100

Let's calculate the percentage change:

Percentage Change = ((10.8 d.e. - 10 d.e.) / 10 d.e.) * 100 = (0.8 d.e. / 10 d.e.) * 100 = 8%

Therefore, the initial price of the suit has changed by 8%.
