What is the number of illiterate persons below the poverty line ?

  • A.2480
  • B.3100
  • C.620
  • D.1000

Answer: C

There are 620 illiterate persons below the poverty line.

40% of males = 8800, so there are 22,000 males. From 11 : 10 : 9 there are 20,000 females and 18,000 children aged 10 and above; children below 10 are 10% of females, 2,000. Total population = 62,000.

\[ \begin{aligned} \text{below poverty line} &= 5\% \times 62000 = 3100 \\ \text{illiterate among them} &= 20\% \times 3100 = 620 \end{aligned} \]

3100 is the whole below-poverty-line group, and 2480 is the literate part of it (80%).
