Contigent's profit percentage was 50% in 2011 and 60% in 2012. The question asks for the percentage increase from 2011 to 2012, so each option can be checked against the standard percentage increase formula, \( \text{Percentage increase} = \frac{\text{New value} - \text{Old value}}{\text{Old value}} \times 100 \).
Applying the formula correctly to the given values of 50% and 60% gives a 20% increase.
So the correct answer is option (B), 20%.
Pollaris earned 35% profit in 2011 and 50% in 2012, giving a combined figure of 85. Contigent earned 40% in 2007 and 35% in 2008, giving a combined figure of 75. The question asks what percentage Pollaris's combined total represents of Contigent's combined total, so each option can be checked against \( \frac{85}{75} \times 100 \).
Working directly from the two totals given in the passage, 85 against 75, produces 113.3%, which matches only the first option.
So the correct answer is option (A), 113.3%.
The question gives Contigent's income for 2008 (₹200 crore) and asks for its profit in 2009. Checking what each option would require shows why none of the specific rupee figures can actually be worked out.
Since a year's profit percentage only tells us profit as a share of that same year's income, and 2009's income is never given, the actual profit for 2009 cannot be calculated.
So the correct answer is option (D), Cannot be determined.
To compare the two companies' overall performance, the question asks for the difference between their average annual profit percentages across all six years, 2007 to 2012.
Pollaris earned 30, 30, 40, 20, 35 and 50 percent profit across the six years, adding to 205, for an average of \( \frac{205}{6} \). Contigent earned 40, 35, 30, 45, 50 and 60 percent, adding to 260, for an average of \( \frac{260}{6} \). The difference between these two averages is \( \frac{260}{6} - \frac{205}{6} = \frac{55}{6} \approx 9.17 \).
So the correct answer is option (C), 9.17.
Pollaris earned 20% profit in 2010 and 35% in 2011. The question asks for the percentage increase from 2010 to 2011, so each option can be checked against \( \frac{35 - 20}{20} \times 100 \).
The rise from 20% to 35% is a jump of 15 percentage points, and measured against the starting value of 20, that comes to \( \frac{15}{20} \times 100 = 75\% \).
So the correct answer is option (B), 75.
