Столяр отремонтировал 32 стула,работая 5ч до обеда и 3ч после обеда.За каждый час столяр ремонтировал одинаковое количество стульев. Сколько стульев отремонтировал столяр до обеда? После обеда?

Answer 1

5 + 3 = 8 ч - всего часов работал
32 : 8 = 4 стула за час
5 * 4 = 20 стульев до обеда
3 * 4 = 12 стульев после обеда

Answer 2

Calculation of the Number of Chairs Repaired by the Carpenter

To calculate the number of chairs repaired by the carpenter before and after lunch, we need to consider the total working hours and the uniform rate at which the carpenter repairs chairs.

The carpenter worked for a total of 5 hours before lunch and 3 hours after lunch, for a total of 8 hours in a day.

Let's assume that the carpenter repairs x chairs per hour.

To find the number of chairs repaired before lunch, we multiply the number of hours worked before lunch (5 hours) by the rate of chairs repaired per hour (x):

Number of chairs repaired before lunch = 5 hours * x chairs/hour

To find the number of chairs repaired after lunch, we multiply the number of hours worked after lunch (3 hours) by the rate of chairs repaired per hour (x):

Number of chairs repaired after lunch = 3 hours * x chairs/hour

Therefore, the carpenter repaired 5x chairs before lunch and 3x chairs after lunch.

Please note that the specific value of x (the rate at which the carpenter repairs chairs) is not provided in the question, so we cannot determine the exact number of chairs repaired before and after lunch without this information.
