Answer:
500 people were surveyed
Explanation:
Given in the question,
42% voted football to be there favourite sport
33% voted baseball to be there favourite sport
25% voted soccer to be there favourite sport
Suppose total number of people who were surveyed = x
if 42% of total people surveyed = 210
then total = x
(42/100) * x = 210
42x = 210 * 100
42x = 21000
x = 21000/42
x = 500
So total number of people who were surveyed = 500
