What is the total number of employees working in the IT department?
-
- 130
- 124
- 143
- 101
- None of these
Correct Option: C
Given :- The total number of employees in the organisation = 520
Ratio of men to women in the organisation = 5 : 3
Number of men in the organisation = 5 x 65 = 325
Number of women in the organisation = 3 x 65 = 195
| Total number of women work in the IT department = 195 x | 2 | = 78 |
| 5 |
| Total number of men work in the IT department = 325 of 20% = 325 x | 1 | = 65 |
| 5 |
∴ The total number of employees working in the IT department = Total number of men working in the IT department + Total number of women working in the IT department
= 78 + 65 = 143
