A Correct answer
Explanation

Coefficient of variation = (Standard Deviation / Mean) * 100. 60 = (24 / Mean) * 100. Mean = 2400 / 60 = 40.

AI explanation

The formula for the coefficient of variation is the standard deviation divided by the arithmetic mean, multiplied by 100. Substituting the given values gives 60 equals 24 divided by the arithmetic mean, multiplied by 100. Rearranging this equation gives the arithmetic mean as 2400 divided by 60. The result is 40.
