The table gives a department-wise breakup. Column totals are: total employees = 1800, male employees = 1020, recently promoted employees = 600. Each cell is that department's percentage share of the column total.
| Department | Employees (of 1800) | Male employees (of 1020) | Recently promoted (of 600) |
|---|---|---|---|
| Accounts | 20% | 5% | 6% |
| Productions | 35% | 50% | 35% |
| IT | 15% | 20% | 26% |
| HR | 12% | 10% | 11% |
| Marketing | 18% | 15% | 22% |
The number of employees promoted from the HR department is approximately what percentage of the number working in that department?
A36.18
B30.56 ✓ Correct
C47.22
D28.16
