According to the Pareto Principle, 20% of inputs typically account for what percentage of the outcome?

• A. 80% of the outcome
• B. 60% of the outcome
• C. 40% of the outcome
• D. 100% of the outcome

Answer: (A)

The main concept being tested is the Pareto Principle, also known as the 80/20 rule. It describes a typical pattern where a small minority of inputs creates the majority of the results. In practical terms, about 20% of causes often generate around 80% of the effects. So, 20% of inputs account for roughly 80% of the outcome. This is a useful heuristic, not a universal law, and the exact split can vary (some systems show 70/30, others 90/10), but the idea remains that a minority of inputs drives most of the results. The other percentages don’t fit this skewed distribution: 60% or 40% would imply a less concentrated impact, and 100% would mean every input contributes equally, which isn’t what the Pareto Principle describes.
