According to a survey conducted in a city, 25% were doctors, 30% engineers, 15% businessmen and rest were illiterates. What is the number of illiterates if the total population of the city is 5000?
Answer: Option B

B
Given: Out of total population, 25% were doctors, 30% engineers, 15% businessmen and rest were illiterates.
Hence, percentage of illiterates =100−(25+30+15)=30%
So, number of illiterates =30% of 5000
=30100×5000
=1500
