Question

If in the next 10 years, the population of wild animals in Antarctica will increase by 2.5% more than that in the rest of the world, what will be the percentage population of wild animals in Antarctica after 10 years?

• A. 9.5%
• B. 11.6%
• C. 15.7%
• D. Cannot be determined

Answer 1

The correct option is D Cannot be determined

Pie charts given in the question present two different data for seven regions namely A1 to A7. Left-hand piechart presents the population distribution of wild animals in seven regions whereas right-hand pie chart presents the land under forest cover distribution in seven regions.
Population density = $\frac{PercentageNumberofAnimals}{PercentageLandAreaUnderForestCover}$

As the increase in the population of the rest of the world is not known, we cannot determine the increase in Antarctica's wildlife population. Hence, option (d) is the answer.
