Question
The ratio of the number of males and females in an
apartment is 14:11. If 25% of the males and 25% of the females read newspapers out of 200 persons, the percentage of the persons who don’t read newspapers is:Solution
Total no. of persons = 200 Males = 200 x (14/25) = 112 and Females = 200 x (11/25) = 88 25% of males who read newspaper = 112 x (25/100) = 28 25% of females who read newspaper = 88 x (25/100) = 22 Therefore no. of persons who do not read newspaper = 200 - (28 + 22) = 150 Required % = 150 x (100/200) = 75%
