In a dorm with 48 inmates, how many shower heads are required?

• A. 2
• B. 3
• C. 4
• D. 5

Answer: (B)

This question hinges on applying the minimum shower facilities ratio. The standard requires one shower head for up to twenty inmates in a dorm setting. With forty-eight inmates, you divide 48 by 20, which equals 2.4. Since you can’t have a fraction of a shower head, you round up to three. So, the minimum number of shower heads needed is three, which can accommodate up to sixty inmates and meets the requirement for a 48-inmate dorm. Two heads would only cover forty inmates, leaving eight without access at the same time, which isn’t sufficient. Four heads would also satisfy the standard, but it isn’t the minimum required.
