Answer 1

1)  15+12+11=38(дн.)-отработано всего
2)   83000:38=2184,21(р../день)-заработок за 1 день
3)   2184,21*15=32763,16(р.)-заработал Вася
4)   2184,21*12=26210,53(р.)-получил Коля
5)   2184,21*11=24026,31(р.)-получил Петя

или 
х  руб./день - заработок работника за один день
15х  руб. - заработок Васи
12х  руб. - заработок Коли
11х  руб. - заработок Пети
Всего получили 83000 рублей.

15х+12х+11х=83000
38х=83000
х=83000:38
х=2184,21

2184,21*15=32763,16(р.) - получил Вася
2184,21*12=26210,53(р.) - получил Коля
2184,21*11=24026,31(р..) - получил Петя

Answer 2

Calculation of Earnings for Each Worker

To calculate the earnings for each worker, we need to determine the daily wage for each worker and then multiply it by the number of days they worked.

Given the following information: - Vasya worked for 15 days. - Kolya worked for 12 days out of 15. - Petya worked for 11 days out of 15. - The total payment for the completed work was 83,000 rubles.

Let's calculate the daily wage for each worker and then determine their earnings.

1. Calculate Vasya's earnings: - Vasya worked for 15 days, so his daily wage would be the total payment divided by the number of days he worked: 83,000 rubles / 15 days = 5,533.33 rubles per day. - Therefore, Vasya earned 5,533.33 rubles per day for 15 days, resulting in a total earning of 83,000 rubles.

2. Calculate Kolya's earnings: - Kolya worked for 12 days out of 15, so his daily wage would be the same as Vasya's: 5,533.33 rubles per day. - Therefore, Kolya earned 5,533.33 rubles per day for 12 days, resulting in a total earning of 66,399.96 rubles.

3. Calculate Petya's earnings: - Petya worked for 11 days out of 15, so his daily wage would also be the same as Vasya's and Kolya's: 5,533.33 rubles per day. - Therefore, Petya earned 5,533.33 rubles per day for 11 days, resulting in a total earning of 60,866.63 rubles.

To summarize: - Vasya earned 83,000 rubles. - Kolya earned 66,399.96 rubles. - Petya earned 60,866.63 rubles.

Please note that the daily wage for each worker is calculated based on the assumption that the total payment of 83,000 rubles is divided equally among the number of days worked by all three workers.
