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?

Answer 1

Answer:

36%

Step-by-step explanation:

Let Total number of people =100;

Total poor people = 60% of 100 =(60*100)/100=60;

Therefore, rich people = 40% of 100 =(40*100)/100=40=40;

Total illiterate people = 40% of total people =(40*100)/100=40;

Among rich, 10% are illiterate = 10% of 40 =(10*100)/40=4;

The number of the illiterate poor population =40−4=36;  

Therefore, illiterate poor =36, total population =100;

Required percentage =(36*100)/100=36%.
