Explanation:

Explanation: Let Total number of people =100;
Total poor people = 60% of 100 =(60*100)/100=60=(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%.
