Question

Подрядчик нанял работника с условием платить за каждый день по 75 коп , за каждый праздничный день удерживают с него по 15 коп,По прошедствии 30 дней работнику следовало выдать 18 руб ,Сколько дней он работал?

Answer 1

Если праздников не было То работник отработавший 30 дней получил 0,75 * 30 =22,5 руб  22,5 - 18 = 4,5 руб       работник отдыхал 5 дней
(30 - 5)*0,75  - 0,15 * 5 = 18,75 - 0,75 = 18,00 руб 

Answer 2

Calculation of Work Days and Payment

To calculate the number of days the worker worked and the total payment, we need to consider the conditions set by the contractor. According to the information provided:

- The worker is paid 75 kopeks for each regular workday. - 15 kopeks are deducted from the worker's payment for each public holiday.

The worker is supposed to receive a total payment of 18 rubles after 30 days of work.

To determine the number of workdays, we can set up the following equation:

Total Payment = (Number of Workdays * 75 kopeks) - (Number of Public Holidays * 15 kopeks)

Let's solve this equation to find the number of workdays:

18 rubles = (Number of Workdays * 75 kopeks) - (Number of Public Holidays * 15 kopeks)

To convert rubles to kopeks, we multiply by 100:

1800 kopeks = (Number of Workdays * 75 kopeks) - (Number of Public Holidays * 15 kopeks)

Now, let's solve for the number of workdays:

1800 = (Number of Workdays * 75) - (Number of Public Holidays * 15)

Since we don't have the exact number of public holidays, we cannot determine the exact number of workdays. However, we can calculate the range of possible workdays based on the given information.

Let's consider the extreme cases: - If there were no public holidays, the worker would have received the full payment of 18 rubles. In this case, the equation becomes: 1800 = (Number of Workdays * 75) - (0 * 15) Solving for the number of workdays: Number of Workdays = 1800 / 75 = 24 - If all 30 days were public holidays, the worker would not receive any payment. In this case, the equation becomes: 0 = (Number of Workdays * 75) - (30 * 15) Solving for the number of workdays: Number of Workdays = (30 * 15) / 75 = 6

Therefore, based on the given information, the worker worked between 6 and 24 days.

Please note that without the exact number of public holidays, we cannot determine the exact number of workdays.
