A district in Karnataka has a population of 3.24 Lakhs and a literacy rate of 75%. Out of the total population, 1.8 Lakh are male are the rest are female. If 70% of the men are literate, then what is the literacy rate among women?

• A. 81.25%
• B. 80%
• C. 78.75%
• D. 77.5%
• E. 76.25%

Answer 1

The correct option is A 81.25%

Ratio of men: women = 1.8 Lakh: 1.44 Lakh = 5: 4
Average literacy rate = $\frac{5\times 70+4\times x}{9}=75\%$
$\Rightarrow$ Female literacy rate, x = $\frac{9\times 75-5\times 70}{4}=81.25\%$
