Question

Soccer-25%

baseball-33%
football-42%
if 210 people said football was their favorite sport to watch, how many people were surveyed?

Answer 1

for football : 42 ...makes .......210 people

baseball : 33 .............makes....x people

cross multiply 42x = 33 x 210

42x = 6930

x = 6930 / 42 = 165 people

soccer : 25 ....which makes y people

football : 42....which makes 210 people

CROSS MULTIPLY.... 42 y = 210 x 25

y = 5250 / 42 = 125

so total people surveyed = 125 + 210 + 165 = 500

you can check answer by this : 42 / 100 x 500 = 210 people.....
