A business percentage of total sales generated by all companies in the same market

• A. ROI
• B. Market share
• C. Reorder point
• D. Marketing concept

Answer: (B)

The concept being tested is market share—the portion of total market sales that a single company accounts for. Market share is calculated as the company’s sales divided by the total sales in the market, then multiplied by 100 to express it as a percentage. This directly describes a business’s percentage of total sales generated by all firms in the same market, which is exactly what the question asks for.

Why this is the best fit: it measures relative size and competitive position, showing how much of the market the company controls compared with others, which is crucial for strategy and benchmarking.

Why the others don’t fit: ROI looks at profitability from an investment rather than market size; a reorder point is an inventory threshold; a marketing concept is a business philosophy about satisfying customer needs, not a metric of market share.
