The Pareto Principle, also known as the 80/20 rule, asserts that approximately 80% of the effects come from 20% of the causes. This principle is often used to illustrate that a small proportion of efforts can lead to a large portion of results.
Let's examine the options provided in the question:
- Option a: 30
- Option b: 40
- Option c: 10
- Option d: 20
According to the Pareto Principle, the percentage of efforts that typically result in the most significant outcomes is 20%. Therefore, the correct choice among the given options is:
d. 20
