The widget factory is pulling items from each batch to test them for quality control. Twenty-four items are pulled randomly from each batch regardless of the size of the batch. A manager records the percentage and the size of the batch in a log. Which of these could be recorded in the log?

9% of 260
6% of 400
20% of 120
25% of 96
12% of 220
15% of 160

Answer 1

6% of 400
20% of 120
25% of 96
15% of 160

Divide 24 by the total to see if you get the percent.
OR multiply the percent by the total to see if you get 24.

Answer 2

Since 24 are always pulled, simply multiply the percentage by the total number of each one and if it equals 24, then it is correct.

9% of 260 = 23.4
6% of 400 = 24
20% of 120 = 24
25% of 96 = 24
12% of 220 = 26.4
15% of 160 = 24
