Question 20

If 30% of viewers of movies G and F left before intermission, how many viewers were left watching these two movies post intermission?

Solution

Number of viewers of movies G and F = 300 + 200 = 500

% of viewers that left = 30%

=> Number of viewers that were left watching these two movies post intermission = $$\frac{(100-30)}{100}\times500$$

= $$70\times5=350$$

=> Ans - (B)
