If 12 clerks can process 480 files in 8 days working 6 hours a day, how many clerks are needed to process 600 files in 5 days working 8 hours a day?
Answer and explanation
Correct answer: C. 18 clerks
- Step 1: Formula: (M1 D1 H1) / W1 = (M2 D2 H2) / W2.
- Step 2: (12 8 6) / 480 = (M2 5 8) / 600.
- Step 3: 576 / 480 = 1.2. (40 M2) / 600 = M2 / 15.
- Step 4: M2 / 15 = 1.2 => M2 = 1.2 * 15 = 18 clerks.
