Calculation of Percentage Reduction in Number of Employees

To calculate the percentage reduction in the number of employees at the company after the modernization of production, we can use the following formula:

Percentage Reduction = ((Initial Number of Employees - Final Number of Employees) / Initial Number of Employees) * 100

Given that the initial number of employees was 240 and the final number of employees after the modernization was 192, we can substitute these values into the formula:

Percentage Reduction = ((240 - 192) / 240) * 100

Calculating this expression, we find that the percentage reduction in the number of employees is 20%.

Therefore, the number of employees at the company was reduced by 20% after the modernization of production.

Calculation of Percentage Difference in Price between Grapes and Raspberries

To calculate the percentage difference in price between grapes and raspberries, we can use the following formula:

Percentage Difference = ((Price of Grapes - Price of Raspberries) / Price of Raspberries) * 100

Given that the price of grapes is 160 rubles per kilogram and the price of raspberries is 200 rubles per kilogram, we can substitute these values into the formula:

Percentage Difference = ((160 - 200) / 200) * 100

Calculating this expression, we find that the percentage difference in price between grapes and raspberries is -20%.

Therefore, grapes are 20% cheaper than raspberries.
