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.

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

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

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?

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

Assume that;-
New(Money deposit)
Left (expenses)
Now we want to know how much I saved.
Deposit (760+280+179)- expense (120+92)=1007.
Rest all you can do the same method and calculate average all 5's.
I hope it helps.
