Correct Answer: B
Solution :
Number of film watchers in city 1 \[=\frac{100}{100-50}\times 3200=6400\] Number of film watchers in city 2 \[=\frac{100}{100-30}\times 3500=5000\] Number of film watchers in city 4 \[=\frac{100}{100-25}\times 5400=7200\] Number of film watchers in city 5 \[=\frac{100}{100-80}\times 2900=14500\] Therefore, the number of film watchers in city 2 is minimum.
