Question

Ціну на товар що коштував 200 грн спочатку підняли на 20% а потім знизили на 20% знайти вартість товару після двох переоцінок

Answer 1

200\10=20 - 10% от начальной цены товара
20*2=40 на 40 гривен увеличили товар.
200+40=240 цена товара после увеличения на 20%
Теперь находим 20% от 240
240\10=24      24 гривны это 10%от 240
24*2=48       48 гривен это 20% от 240
240-48=192 гривны после увеличения и уменьшения цены товара на 20%

Answer 2

Calculation of the Final Price

To calculate the final price of a product that initially cost 200 UAH and underwent two price changes (a 20% increase followed by a 20% decrease), we can follow these steps:

1. Calculate the price after the 20% increase: - The initial price of the product is 200 UAH. - To increase the price by 20%, we multiply the initial price by 1 + (20/100) = 1.2. - Therefore, the price after the 20% increase is 200 UAH * 1.2 = 240 UAH.

2. Calculate the price after the 20% decrease: - The price after the 20% increase is 240 UAH. - To decrease the price by 20%, we multiply the increased price by 1 - (20/100) = 0.8. - Therefore, the final price after the 20% decrease is 240 UAH * 0.8 = 192 UAH.

The final price of the product after the two price changes is 192 UAH.

Please note that the calculation assumes that the price changes are applied successively and not simultaneously.
