Question

Population density of wild animals in Europe is how many times that of the population density of wild animals in Russia?

• A. 1.375
• B. 1.49
• C. 1.57
• D. 1.64

Answer 1

The correct option is A 1.375

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 = $\frac{PercentageNumberofAnimals}{PercentageLandAreaUnderForestCover}$

This is a simple calculation.
Population density of Russia = 1 while population density of Europe = 1.375.
Hence, option (a) is the answer.
