Question

в городских новостях прозвучало сообщение: цена одного товара, пользовавшегося повышеным спросом, в течении года выросла с 18 до 28р почти на 30%. верный ли вывод сделан о росте цены?

Answer 1

Вывод неверный. Факттический рост цены составил

(28/18 - 1) * 100% = 10/18 * 100% ≈ 55,6%

Answer 2

Этот вывод не верен, т.к цена выросла не на 30%, а на ((28 * 100)/18) - 100% = приблизительно на 56%.

 

Answer 3

The Price Increase of a Popular Product

According to a recent news report, the price of a particular product that has experienced high demand has increased from 18 rubles to 28 rubles over the course of a year, representing an almost 30% increase. The question is whether the conclusion drawn about the price increase is accurate.

Analyzing the Price Increase

To determine the accuracy of the conclusion, we need to calculate the percentage increase in price and compare it to the reported figure of 30%.

The formula to calculate the percentage increase is:

Percentage Increase = ((New Price - Old Price) / Old Price) * 100

Using this formula, let's calculate the percentage increase:

((28 - 18) / 18) * 100 = 55.56%

The calculated percentage increase is approximately 55.56%, which is significantly higher than the reported figure of 30%. Therefore, the conclusion made about the price increase is not accurate.

Possible Explanations

There could be several reasons for the discrepancy between the reported figure and the calculated percentage increase. It's important to consider factors such as rounding errors, different calculation methods, or potential inaccuracies in the reported information.

Additionally, it's worth noting that the reported figure of 30% is an approximation, and the actual percentage increase may vary slightly. It's always advisable to verify the accuracy of the information from reliable sources or consult with experts in the field.

Conclusion

In conclusion, based on the calculations, the reported figure of a 30% price increase for the mentioned product does not align with the actual percentage increase of approximately 55.56%. It is important to verify the accuracy of the information and consider possible factors that may contribute to the discrepancy.
