Who knows the answer to the last question of the 20 1 1 property manager exam on property practice?

Remember some questions about understanding, roughly as follows:

Case: There are four 30-storey houses in a residential area, and the bidding documents require strict management. . . There are doorposts and control centers, which need to be on duty 24 hours a day. . .

Question 1. Assuming that the patrol time of each floor is 1 minute (excluding the arrival delay of the middle floor), it will be conducted every hour, so how many patrol employees are needed for each shift in the community?

Question 2. Assuming that employees work 20.83 days a month and 30 days a month, they will be arranged according to the comprehensive working system, and the overtime of employees will not exceed 36 hours a month; What is the longest working time of employees per month? How many employees (integer) does the gatepost need at least?

Question 3. The control center arranges 8 employees, assuming 30 days per month, with the basic salary of 1.500 yuan per person per month and working for 2 1.75 days. Arrange the work according to the comprehensive working system, with the overtime coefficient of 1.5 times (assuming there are no other legal holidays), and the overtime of employees shall not exceed 36 hours per month; How much is the overtime pay per employee per hour? How much overtime does each employee work every month? What is the actual monthly income and salary of employees? (Take two decimal places)

I wonder if it is feasible to answer this question. The control center is equipped with two people according to the fire control requirements, but it is not mentioned in the case and topic, as follows:

1. solution: 4*30= 120 floors, each floor needs 1 minute = 120 minutes, and it is patrolled once every hour, and at least 120/60=2 people are needed.

2. Solution: (1)20.83*8 hours/day = 167 hours The maximum working time is: 167 hours +36 hours overtime =203 hours.

(2) The required working time of the post is 30 days *24 hours =720 hours, and the required number is 720/203=4.

3. Solution: (1) The overtime pay is: 1500/2 1.75 days /8 hours * 1.5 times = 12.93 yuan/hour.

(2) The working time required for the post is: 30 days *24 hours *2 people = 1440 hours. The normal working hours provided by employees are: 2 1.75*8 people *8 hours = 1392 hours. The required overtime time is: 1440- 1392 hours.

(3) Overtime pay 12.93 yuan/hour *6 hours =77.58 yuan. Actual income is: basic salary 1500 yuan+overtime salary 77.58 yuan = 1577.58 yuan.
