Correct Answer: 88%
Solution : Total population = 25,000 Females = 25000 × $\frac{1}{5}$ = 5,000 Males = 25000 – 5000 = 20,000 Uneducated People = 20,000 × $\frac{5}{100}$ + 5000 × $\frac{40}{100}$ = 1000 + 2000 = 3000 Educated People = 25000 – 3000 = 22,000 Required Percentage = $\frac{22000}{25000}$ x 100 = 88% Hence, the correct answer is 88%.
