1 Answer - Sort by: Date | Rating
The ratio is,
10/50 = 15/x
If you cross multiply you will get
10x = 50 x 15 = 750
Divide both sides by 10 and get
x = 75. 75 people would have been surveyed
10/50 = 15/x
If you cross multiply you will get
10x = 50 x 15 = 750
Divide both sides by 10 and get
x = 75. 75 people would have been surveyed
