Question

In a city 40 percent of the people are illiterate and 60 percent are poor. Among the rich, 10 percent are illiterate. What percentage of the poor population is illiterate? Select one: a. 40 percent b. 60 percent c. 36 percent d. None of these

Answer 1

Answer:

60

Step-by-step explanation:

Let the population of the city be 100.

Total illiterate people = 40

Poor people = 60

Rich people = 40

Illiterate rich people

= 40 × 10

= 4

100

∴ Illiterate poor people

= 40 – 4 = 36

∴ Required per cent

=

36

× 100 = 60%

60
