How many years of service are required to display four service stripes?

• A. 12
• B. 16
• C. 20
• D. 24

Answer: (B)

Service stripes indicate years of service, and in this system each stripe represents four years. With four stripes, you multiply four years by four stripes to get 16 years of service. The other options would correspond to different numbers of stripes (three stripes would be 12 years, five stripes would be 20 years, six stripes would be 24 years). So four stripes = 16 years.
