Show answer & explanation
Correct answer: B
Given: Total appeared candidates = 45000; Total qualified candidates = 9000.
Qualified from B and C = (16% + 7%) of 9000 = 23% of 9000 = 0.23 × 9000 = 2070.
Appeared from B and C = (11% + 8%) of 45000 = 19% of 45000 = 0.19 × 45000 = 8550.
Required percentage = (Qualified from B and C) / (Appeared from B and C) × 100 = (2070 / 8550) × 100.
Simplify: (0.23 × 9000) / (0.19 × 45000) = (23/100 × 9000) / (19/100 × 45000) = (23 × 9000) / (19 × 45000) = 23 / (19 × 5) = 23/95 ≈ 0.2421 → 24.21%.
Answer: 24.21% (this matches the option 24.21).
