The difference between the illiterate population and the literate population of City C is
A8.5 lakh
B9.5 lakh ✓ Correct
C10.5 lakh
D20.5 lakh
Correct answer: (B) 9.5 lakh
Explanation
The answer is 9.5 lakh.
City C has 21 percent of the 1.5 crore population, which is 31.5 lakh.
Its literate males are 20 percent of 40 lakh and its literate females are 12 percent of 25 lakh, giving 8 plus 3, or 11 lakh.
So its illiterates are 31.5 minus 11, which is 20.5 lakh.
The difference between illiterates and literates is 20.5 minus 11.
That is 9.5 lakh.
So the answer is 9.5 lakh.
