Question

При хранении картофеля в погребе в течении 6 месяцев сохраняются приблизительно 85% первоначальной массы картофеля. Сколько килограммов картофеля нужно заложить в погреб, чтобы через 6 месяцев там оставалось 680 кг картофеля?

Answer 1

85 % -  680 кг

100 % -  ? кг

680 * 100 : 85 = 800 кг картофеля нужно заложить.

Answer 2

Calculating the Amount of Potatoes Needed for Storage

To calculate the amount of potatoes needed to ensure that 680 kg remain after 6 months of storage, we can use the information that approximately 85% of the initial mass of potatoes is preserved during this period.

Given that 85% of the initial mass is preserved, we can use the following formula to calculate the initial mass of potatoes needed:

Initial Mass of Potatoes = Final Mass / Preservation Rate

Substituting the given values: Initial Mass of Potatoes = 680 kg / 0.85

Calculation

Initial Mass of Potatoes = 800 kg

Therefore, approximately 800 kg of potatoes should be stored in the cellar to ensure that 680 kg remain after 6 months.

This calculation is based on the preservation rate of 85% over a 6-month period
