Correct answer: A

Concept

When a total is divided into a percentage group and then by a ratio, multiply the group percentage by the required ratio share. If a known subgroup equals a fraction p of the total, then total = known subgroup ÷ p.

Application

  1. For state C, 24% of the population is below the poverty line, so 100% − 24% = 76% is above the poverty line.

  2. Among the population above the poverty line, the male-to-female ratio is 2 : 3. Therefore, the male share is 2/(2 + 3) = 2/5.

  3. Thus, males above the poverty line form 76% × 2/5 = 30.4% = 0.304 of the total population.

  4. Let the total population be P million. Then 0.304P = 1.9, so P = 1.9/0.304 = 6.25 million.

Cross-check

  1. For a total of 6.25 million, 76% is 4.75 million above the poverty line.

  2. The male share is 2/5, and 2/5 of 4.75 million is 1.90 million, matching the given value.

Therefore, the total population of state C is 6.25 million.
