4.
What is the pooled average of the total number of employees of all categories in the year 1997?
Answer: Option
Explanation:
Total number of employees of various categories working in the Company in 1997 are:
| Managers | = (760 + 280 + 179) - (120 + 92) = 1007. |
| Technicians | = (1200 + 272 + 240) - (120 + 128) = 1464. |
| Operators | = (880 + 256 + 240) - (104 + 120) = 1152. |
| Accountants | = (1160 + 200 + 224) - (100 + 104) = 1380. |
| Peons | = (820 + 184 + 152) - (96 + 88) = 972. |
Pooled average of all the five categories of employees working in the Company in 1997
| = | 1 | x (1007 + 1464 + 1152 + 1380 + 972) |
| 5 |
| = | 1 | x (5975) |
| 5 |
= 1195.

We must consider only 1997. According to question.
And pooled means : present employees in 1997.

Guys.. Here the data not showing the the no of employees in corresponding years. Here he has given only the no of new employees added and no of employees left. So, to find the increased employees average(pooled average means average of the increased employees), we should find the number of employees for that year. In order to find that we are calculating the members from the established year of the company.
Ex: In mechanics:
When the company started in the year 1995 the no of employees joined were 760.
In 1996 no.of employees are 760+280(new)-120(left) = 920,
In 1997 ,, , ,,, , , 920+179(new)-92(left) = 1007.
So pooled employees in the managers are 1007.
Similarly we can find the avg of all the categories.

Can anyone explain what is pooled average? and why they are calculating all the years. They have asked only for the year 1997.

Why are we not considering data of the year 1997 as according to question it is asking "pooled average. In the year 1997 " only? please do solve this query.

"What is the average number of people per department in 1997?" or you can make it "per category". The original question is ambiguous and confusing.
