Question:easy

The bar graph below shows the failure rates, number of failures per thousand units, of different electronic components.
ComponentFailure Rate
Picture Tubes15
Signal Devices16
Capacitors20
Integrated Circuits30
Printed Circuit Boards33
Hybrid Micro Circuits40
Which of the following components has a failure rate 25% more than that of signal devices?

Show Hint

Add 25% of the signal devices failure rate, 16, to itself and match the result on the chart.

  • Pictures tubes
  • Capacitors
  • Integrated circuits
  • Printed Circuits boards
Show Solution

The Correct Option is B

Solution and Explanation

Test each option's % increase over 16: Picture tubes(15) is a decrease. Capacitors(20): (20-16)/16=25%. Integrated circuits(30): 87.5%. PCB(33): 106.25%. Only Capacitors matches 25%.

Final Answer: Capacitors, option (2).
