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.

Why not taking all the amounts?

It was asked only for 1997, so why consider three consecutive years?

For which of the above-mentioned categories the percentage increase in the number of employees working in the company from 1995 to 2000 was the maximum?

@Sheik.
1/5 is the number of categories, Average = number of all employees/ number of categories (hence: 1/5x (5975).

A pooled average is like blending different averages to get an overall average.
