Show answer & explanation
Correct answer: C
Solution: Compute the number of qualified candidates from states B and D, and the number of candidates appeared from state C, then form and simplify the ratio.
Qualified from state B = 16% of 9000 = 0.16 × 9000 = 1440.
Qualified from state D = 21% of 9000 = 0.21 × 9000 = 1890.
Total qualified from B and D = 1440 + 1890 = 3330.
Appeared from state C = 8% of 45000 = 0.08 × 45000 = 3600.
Form the ratio: 3330 : 3600. Divide both terms by 30 → 111 : 120. Divide both terms by 3 → 37 : 40.
Answer: 37 : 40
