What percentage of fields had DRP levels substantially higher than the target?

• A. 30%
• B. 20%
• C. 5%
• D. 40%

Answer: (B)

The main idea is to determine what portion of fields show DRP levels that are notably above the target. To find that, you count how many fields meet the “substantially higher” criterion, then divide by the total number of fields and multiply by 100 to get a percentage.

In this case, the data indicate that 20 out of 100 fields exceed the target by the defined amount, giving 20%. That means one-fifth of the fields have DRP levels substantially higher than the target. The same calculation would apply if you had a different total—e.g., 40 out of 200 fields is also 20%.
