Finding the Average Number of Employees
The question asks us to find the average number of employees present for the last three days of a week based on the data provided in the table.
| Days | Number of Employees |
|---|---|
| D1 | 1000 |
| D2 | 1400 |
| D3 | 1800 |
| D4 | 1200 |
| D5 | 1235 |
| D6 | 1465 |
The table shows the number of employees present from Day 1 (D1) to Day 6 (D6). We need to find the average for the last three days.
Identifying the Last Three Days
From the table, the days are D1, D2, D3, D4, D5, and D6. The last three days are D4, D5, and D6.
Number of Employees on the Last Three Days
- Number of employees on Day 4 (D4) = 1200
- Number of employees on Day 5 (D5) = 1235
- Number of employees on Day 6 (D6) = 1465
Calculating the Average Number of Employees
To find the average number of employees for these three days, we need to sum the number of employees for each day and then divide by the number of days (which is 3).
First, let's find the sum of employees for the last three days:
\(\text{Sum} = \text{Employees on D4} + \text{Employees on D5} + \text{Employees on D6}\)
\(\text{Sum} = 1200 + 1235 + 1465\)
\(\text{Sum} = 3900\)
Next, we calculate the average:
\(\text{Average} = \frac{\text{Sum}}{\text{Number of days}}\)
\(\text{Average} = \frac{3900}{3}\)
\(\text{Average} = 1300\)
So, the average number of employees present for the last three days of the week is 1300.
