Answer:
48 people
Explanation:
Count all the numbers in the chart
12 + 8 + 10 = 30
First: 12 + 8 = 20
Next: 20 + 10 = 30
Divide 120 by 30 to get 4, which is how many people of a number is chosen
If a number is 12, and the people per number is 4
12 x 4 = 48
(BTW, If I don't get this right, I'm gonna cringe)
