The sum of 6 numbers is 372. Find their average.

Appeared in: DSSSB 14 August 2024

Explanation

The average, or arithmetic mean, represents the central value of a set of numbers.
The formula for the average is the sum of the values divided by the count of the values.
Given the sum is 372 and there are 6 numbers, the calculation is Average = Sum / Count.
Substituting the values: Average = 372 / 6.
Performing the division gives the result of 62.

Option A: This is incorrect. An average of 60 would require the sum of the six numbers to be 360 (60 × 6), not 372.
Option B: This is incorrect. An average of 61 would require the sum of the six numbers to be 366 (61 × 6), not 372.
Option C: This is incorrect. An average of 63 would require the sum of the six numbers to be 378 (63 × 6), not 372.

Clinical Relevance

Nursing practice connection: This is primarily an exam-oriented knowledge point with limited direct bedside application, so retain Calculating the arithmetic mean (average) of a set of numbers as background academic context rather than a clinical decision trigger.
Calculating averages is a fundamental mathematical skill essential in many fields, including nursing, for tasks like averaging vital signs over time or calculating mean medication dosages.
This skill forms the basis for more complex statistical analysis used in clinical research, quality improvement, and evidence-based practice.
What if the sum was 420? If the sum of the 6 numbers was 420, then the average would be 420 / 6 = 70.

How to Approach the Question

First, carefully read the question to identify the given information: the sum of the numbers is 372, and the count of the numbers is 6.
Next, identify what the question is asking for: the average.
Recall the fundamental formula for calculating an average: Average = Sum of values / Count of values.
Substitute the given numbers into the formula: Average = 372 / 6.
Perform the division calculation to find the result.
Finally, match your calculated result (62) with the provided options to select the correct answer.
