| Year | ||||||||||
| Managers | Technicians | Operators | Accountants | Peons | ||||||
| New | Left | New | Left | New | Left | New | Left | New | Left | |
| 1995 | 760 | - | 1200 | - | 880 | - | 1160 | - | 820 | - |
| 1996 | 280 | 120 | 272 | 120 | 256 | 104 | 200 | 100 | 184 | 96 |
| 1997 | 179 | 92 | 240 | 128 | 240 | 120 | 224 | 104 | 152 | 88 |
| 1998 | 148 | 88 | 236 | 96 | 208 | 100 | 248 | 96 | 196 | 80 |
| 1999 | 160 | 72 | 256 | 100 | 192 | 112 | 272 | 88 | 224 | 120 |
| 2000 | 193 | 96 | 288 | 112 | 248 | 144 | 260 | 92 | 200 | 104 |
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.

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.

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

Employees at present = sum of employees till the given year.

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