Question

Цену на товар сначала снизили на 10 %,а через некоторое время ещё на 10%.такой ли была бы цена этого товара ,если бы её сразу снизили на 20 %?

Answer 1

Допустим начальная цена товара 100грн.
1) 10% от 100грн
100*10/100=10грн
Значит после первой скидки 100-10=90 гривен стоил товар.
10% от 90грн
90*10/100=9грн
После второй скидки 90-9=81 гривна стал стоить товар.
т.е. общая скидка составила 10+9=19 грн
2) а если сразу снизить на 20 % от 100 грн
20*100/100=20(грн)
Цена товара 100-20=80грн

Вывод если сразу снизить на 20% цену товара, то она будет отличаться от варианта номер 1.

Answer 2

Calculating the Final Price After Consecutive Discounts

To calculate the final price after consecutive discounts, we can use the formula:

Final Price = Original Price × (1 - Discount 1) × (1 - Discount 2)

Where Discount 1 and Discount 2 are the percentages of the first and second discounts, respectively.

Applying the Given Discounts

Given: - First discount: 10% - Second discount: 10%

Let's calculate the final price after these consecutive discounts using the formula mentioned above.

Final Price = Original Price × (1 - 0.10) × (1 - 0.10)

Calculation

Final Price = Original Price × 0.9 × 0.9

Now, let's calculate the final price if the original price was immediately discounted by 20%.

Immediate 20% Discount

If the original price was immediately discounted by 20%, the final price can be calculated using the formula:

Final Price = Original Price × (1 - 0.20)

Calculation

Final Price = Original Price × 0.80

So, the final price after an immediate 20% discount would be 80% of the original price.

This calculation assumes that the discounts are applied to the original price without compounding.
