Mean of 5 numbers is 12. Their sum equals:

To find the sum of a set of numbers when the mean and the count are known, we use the fundamental formula for the arithmetic mean: $$\text{Mean} = \frac{\text{Sum of values}}{\text{Number of values}}$$ ### **Step 1: Identify the given values** * Number of values ($n$) = $5$ * Mean = $12$ ### **Step 2: Rearrange the formula** To isolate the sum, we multiply both sides of the equation by the number of values: $$\text{Sum} = \text{Mean} \times \text{Number of values}$$ ### **Step 3: Calculate the final sum** $$\text{Sum} = 12 \times 5$$ $$\text{Sum} = 60$$ Therefore, the sum of the 5 numbers is **60**.
