Question:medium
The bar graph below shows the failure rates, number of failures per thousand units, of different electronic components.
Component Failure Rate Picture Tubes 15 Signal Devices 16 Capacitors 20 Integrated Circuits 30 Printed Circuit Boards 33 Hybrid Micro Circuits 40
For the equipments using Integrated Circuit Board: 400, Capacitors: 240 and Printed Circuits boards: 120 to run with minimum downtime, how many spares should be kept in the store respectively?

| Component | Failure Rate |
|---|---|
| Picture Tubes | 15 |
| Signal Devices | 16 |
| Capacitors | 20 |
| Integrated Circuits | 30 |
| Printed Circuit Boards | 33 |
| Hybrid Micro Circuits | 40 |
Show Hint
Multiply each equipment count by its failure rate per thousand, then round any fraction up.

- 5, 12, 4
- 12, 4, 4
Show Solution
The Correct Option is B
Solution and Explanation
Per-unit failure fractions: ICB 0.03x400=12; Capacitors 0.02x240=4.8 -> 5; PCB 0.033x120=3.96 -> 4.
Final Answer: 12, 5, 4, option (2).
