Question

A cinema has 3 screens

Answer 1

Well ok lets work this out to figure this out this is what we do:

There are 500 visitors

41% went to screen 1:

500 x .41 = 205 people

25% went to screen 2:

500 x .25 = 125 people 

And the rest went to screen to so:

(205 + 125) - 500 = 170

So your answer would be:

205 went to screen 1

125 went to screen 2

170 went to screen 3
