Question

Із 200кг чайного листа одержали 8кг чаю. Скільки відсотків своєї маси втрачає чайний лист у процесі сушіння.

Answer 1

200 кг - 100%
8 кг -х%
х=800/200=4%
Отже, лист втрачає 96% своєї маси

Answer 2

Calculation of Tea Leaf Loss during Drying

To calculate the percentage of tea leaf mass lost during the drying process, we can use the given information that 200 kg of tea leaves yielded 8 kg of tea.

Let's assume that the initial mass of the tea leaves before drying is M1, and the mass of the tea obtained after drying is M2. We can set up the following equation:

M1 - M2 = Mass of tea leaf lost during drying

Given that M1 = 200 kg and M2 = 8 kg, we can substitute these values into the equation:

200 kg - 8 kg = Mass of tea leaf lost during drying

Simplifying the equation:

192 kg = Mass of tea leaf lost during drying

To calculate the percentage of tea leaf mass lost during drying, we can use the formula:

Percentage of mass lost = (Mass of tea leaf lost during drying / Initial mass of tea leaves) * 100

Substituting the values:

Percentage of mass lost = (192 kg / 200 kg) * 100

Calculating the percentage:

Percentage of mass lost = 96%

Therefore, the tea leaf loses 96% of its mass during the drying process.
