The Correct Option is C
Solution and Explanation
Sum in Year 1: $4.6 + 5.8 + 3.11 + 10.6 = 24.11$ billion
Sum in Year 3: $18.7 + 21.2 + 7.7 + 29.8 = 77.4$ billion
Increase = $77.4 - 24.11 = 53.29$ billion
Percentage increase = $\frac{53.29}{24.11} \times 100 \approx 221%$
Sum in Year 3: $18.7 + 21.2 + 7.7 + 29.8 = 77.4$ billion
Increase = $77.4 - 24.11 = 53.29$ billion
Percentage increase = $\frac{53.29}{24.11} \times 100 \approx 221%$

The Correct Option is B
Solution and Explanation
Sum of E over 3 years: $10.6 + 17.4 + 29.8 = 57.8$ billion
Sum of F over 3 years: $7.8 + 25.3 + 60.1 = 93.2$ billion
Ratio = $57.8 : 93.2 \approx 19 : 31$
Sum of F over 3 years: $7.8 + 25.3 + 60.1 = 93.2$ billion
Ratio = $57.8 : 93.2 \approx 19 : 31$

The Correct Option is A
Solution and Explanation
Total in Year 2 = $7.5 + 12.5 + 5.6 + 17.4 + 25.3 = 68.3$ billion

Verified By Collegedunia
The Correct Option is B
Solution and Explanation
Sum (A,B,C) Year 2 = $7.5 + 12.5 + 5.6 = 25.6$ billion
Sum (D,E,F) Year 2 = $17.4 + 25.3 = 42.7$ billion
Difference = $42.7 - 25.6 = 17.1$ billion
Percentage difference = $\frac{17.1}{21.1} \times 100 \approx 81%$ (average as base)
Sum (D,E,F) Year 2 = $17.4 + 25.3 = 42.7$ billion
Difference = $42.7 - 25.6 = 17.1$ billion
Percentage difference = $\frac{17.1}{21.1} \times 100 \approx 81%$ (average as base)
