Department202120222023Total
HR40—50140
IT8090—270
Finance—6070180
Total170200220590

What is the number of employees in the HR department in the year 2022?

Cevap: 50 employees

Cevap

The number of employees in the HR department in 2022 is 50.
The row total for HR is 140. Subtracting the known figures for 2021 (40) and 2023 (50) from 140 yields 50 employees for 2022.

Adım Adım Çözüm

1
Examine the row corresponding to the HR department.
Known HR employees in 2021 = 40, 2023 = 50, and Total HR employees = 140.
The row total equals the sum of values across all three years.
2
Calculate the missing 2022 HR value.
140 - (40 + 50) = 50 employees.
Subtracting the sum of 2021 and 2023 values from the total gives the missing value for 2022.
