A data analyst is examining sales data for a retail company across three regions: North, South, and West. The analyst wants to determine the sales contribution of each region to the total company sales. The data for the last fiscal year is as follows: North Region: Sales = $2,500,000 South Region: Sales = $3,500,000 West Region: Sales = $4,000,000 What percentage of total sales does the North Region contribute?
- A40%
- B25%
- C35%
- D30%
Show answer & explanationAnswer & explanation
Correct answer: B. 25%
First, calculate the total sales for the company: $2,500,000 (North) + $3,500,000 (South) + $4,000,000 (West) = $10,000,000. Then, divide the North Region's sales by the total sales and multiply by 100 to get the percentage: ($2,500,000 / $10,000,000) * 100% = 0.25 * 100% = 25%.
Why the other options are wrong
- A. This is the percentage for the West Region.
- C. This is close to the South Region's actual percentage (35%).
- D. This is the percentage for South Region if it were $3,000,000.
Percentage Contribution
Percentage contribution measures the proportion of a specific component relative to a total sum, expressed as a percentage.
- Calculated as (Part / Whole) * 100%.
- Useful for understanding relative importance or share.
- The sum of all percentage contributions should equal 100%.
Memory trick: Part to Whole, then Percent's Goal!
