Problem Analysis

Two carpenters worked together and earned a total of 280 rubles. One of them worked for 14 days, 7 hours per day, while the other worked for 7 days, 6 hours per day. We need to determine how much each carpenter earned if they receive an equal amount for one hour of work.

Solution

To solve this problem, we can calculate the total number of hours worked by each carpenter and then divide the total earnings equally among them.

Let's calculate the total number of hours worked by the first carpenter: - Number of days worked: 14 - Number of hours worked per day: 7 - Total hours worked by the first carpenter: 14 * 7 = 98 hours

Now, let's calculate the total number of hours worked by the second carpenter: - Number of days worked: 7 - Number of hours worked per day: 6 - Total hours worked by the second carpenter: 7 * 6 = 42 hours

Next, let's calculate the earnings per hour for each carpenter: - Total earnings: 280 rubles - Total hours worked by both carpenters: 98 + 42 = 140 hours - Earnings per hour: 280 / 140 = 2 rubles per hour

Finally, let's calculate the earnings for each carpenter: - Earnings for the first carpenter: 98 hours * 2 rubles per hour = 196 rubles - Earnings for the second carpenter: 42 hours * 2 rubles per hour = 84 rubles

Therefore, the first carpenter earned 196 rubles, and the second carpenter earned 84 rubles.

Answer: The first carpenter earned 196 rubles, and the second carpenter earned 84 rubles.
