The following table presents the number of employees recruited for five different positions/posts of Administrators, Analysts, Programmers. Testers and Peons (R) in an IT company and those who left (L) the company during the years 2016 - 2021. Based on the data in the table, answer the questions: (Year of foundation of the Company is 2016) Year-Wise Distribution of Employees Position Administrators Analysts Programmers Testers Peons Year R L R L R L R L R L 2016 380 - 600 - 440 - 580 - 410 2017 140 60 136 60 128 52 100 50 92 48 2018 90 46 120 64 120 60 112 52 76 44 2019 74 44 118 48 104 50 124 48 98 40 2020 80 36 128 50 96 56 136 44 112 60 2021 96 48 144 56 124 72 130 46 100 52
The pooled sum of the total number of employees working for all the five positions in the company at the end of the year 2018 is

Calculating the Pooled Sum of Employees at the End of 2018
This question asks for the total number of employees across all five positions in the IT company at the end of the year 2018. The table provides data on the number of employees recruited (R) and those who left (L) each year from 2016 to 2021 for Administrators, Analysts, Programmers, Testers, and Peons. Since the company started in 2016, the number of employees at the beginning of 2016 was zero.
Understanding Employee Count at Year End
The number of employees for a specific position at the end of a given year can be calculated by taking the number of employees at the end of the previous year, adding the number recruited during the current year, and subtracting the number who left during the current year.
Mathematically, for a specific position 'pos' and year 'Y':
Employee Count at End of Year Y = Employee Count at End of Year (Y-1) + Recruited in Year Y - Left in Year Y
For the first year (2016), the count is simply the number recruited minus the number who left, as the count at the end of 2015 was 0.
Employee Count at End of Year 2016 = Recruited in 2016 - Left in 2016
Step-by-Step Calculation for Each Position up to the End of 2018
We will calculate the number of employees for each position year by year, starting from 2016, and accumulate the numbers until the end of 2018.
| Position | End of 2016 (R - L) | End of 2017 (End 2016 + R$_{2017}$ - L$_{2017}$) | End of 2018 (End 2017 + R$_{2018}$ - L$_{2018}$) |
|---|---|---|---|
| Administrators | $380 - 0 = 380$ | $380 + 140 - 60 = 460$ | $460 + 90 - 46 = 504$ |
| Analysts | $600 - 0 = 600$ | $600 + 136 - 60 = 676$ | $676 + 120 - 64 = 732$ |
| Programmers | $440 - 0 = 440$ | $440 + 128 - 52 = 516$ | $516 + 120 - 60 = 576$ |
| Testers | $580 - 0 = 580$ | $580 + 100 - 50 = 630$ | $630 + 112 - 52 = 690$ |
| Peons (R) | $410 - 0 = 410$ | $410 + 92 - 48 = 454$ | $454 + 76 - 44 = 486$ |
Calculating the Pooled Sum at the End of 2018
The pooled sum of the total number of employees working for all five positions at the end of the year 2018 is the sum of the employee counts for each position at the end of 2018.
Pooled Sum = Employees (Administrators) + Employees (Analysts) + Employees (Programmers) + Employees (Testers) + Employees (Peons)
Pooled Sum = $504 + 732 + 576 + 690 + 486$
Let's add these values:
- $504 + 732 = 1236$
- $1236 + 576 = 1812$
- $1812 + 690 = 2502$
- $2502 + 486 = 2988$
The total pooled sum of employees at the end of 2018 is 2988.
Revision Table: Employee Count Calculation and Pooled Sum
Here is a summary of the employee counts for each position at the end of 2018:
| Position | Employees at End of 2018 |
|---|---|
| Administrators | 504 |
| Analysts | 732 |
| Programmers | 576 |
| Testers | 690 |
| Peons (R) | 486 |
Total Pooled Sum = $504 + 732 + 576 + 690 + 486 = 2988$
Additional Information: Data Interpretation and Employee Dynamics
This problem involves interpreting data presented in a table format. The key is to understand that the number of employees at the end of a period depends on the starting number, additions (recruitment), and subtractions (employees leaving). Cumulative calculation is necessary to track the employee count over multiple years. This type of analysis helps companies understand workforce size trends, recruitment needs, and retention challenges over time for different positions.
- The 'R' column represents employees joining the company in that year.
- The 'L' column represents employees leaving the company in that year.
- The net change in employee count each year is 'R' minus 'L'.
- The total number of employees at any point is the sum of all net changes from the company's foundation until that point.
