Frank Bartlett · Answer 1

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

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.
