Show answer & explanation
Correct answer: C
Extract data (Birth Rates): Q = 8.3, R = 7.6, S = 6.8.
Analyze Statement I: Is Q (8.3) 9.2% more than R (7.6)?
Difference = 8.3 - 7.6 = 0.7. % Increase = (0.7 / 7.6) × 100 ≈ 9.21%. Statement I is correct.
Analyze Statement II: Is R (7.6) 11.76% more than S (6.8)?
Difference = 7.6 - 6.8 = 0.8. % Increase = (0.8 / 6.8) × 100 ≈ 11.76%. Statement II is correct.
Analyze Statement III: Is Q (8.3) 32% more than S (6.8)?
Difference = 8.3 - 6.8 = 1.5. % Increase = (1.5 / 6.8) × 100 ≈ 22.05%. Statement III is incorrect.
Since I and II are correct, the answer is "Both I and II".
Final Answer: Option C
