Question
The multi-level hierarchical pie chart shows the population of animals in a reserve forest. The correct conclusions from this information are:(i) Butterflies are birds
(ii) There are more tigers in this forest than red ants
(iii) All reptiles in this forest are either snakes or crocodiles
(iv) Elephants are the largest mammals in this forest
(ii) There are more tigers in this forest than red ants
(iii) All reptiles in this forest are either snakes or crocodiles
(iv) Elephants are the largest mammals in this forest
Correct answer
(D) (i), (ii) and (iii) only
Solution
Based on the hierarchical pie chart:
1.Conclusion (i): The 'Butterfly' segment is a sub-category of the 'Bird' segment. Therefore, according to the chart, butterflies are classified as birds. (True)
2.Conclusion (ii): The 'Tiger' segment (part of Mammals) occupies a larger portion of the pie chart compared to the 'Red ant' segment (part of Insects). Specifically, the Tiger segment spans approximately units of the outer ring, while the Red ant segment spans unit. Thus, there are more tigers than red ants. (True)
3.Conclusion (iii): The 'Reptile' segment is entirely partitioned into 'Snake' and 'Crocodile'. This means all reptiles in the forest are either snakes or crocodiles. (True)
4.Conclusion (iv): The pie chart represents population distribution, not the physical size of the animals. There is no information to support the claim that elephants are the largest mammals. (False)
Thus, conclusions (i), (ii), and (iii) are correct.Continue learning with Success Tracker
