Question 51.There are ten animals-two each of lion, panther, bison, bear, and deer-in a zoo. The enclosures in the zoo are named A, B, C, D and E and each enclosure is allotted to one of the following attendants John, Manish, Shailendra, Shalini and Rocky. Two animals of different species are housed in each enclosure. A lion and a deer cannot be together. A panther cannot be with either a deer or a bison. Shalini attends to animals from among bison, deer, bear and panther only. Manish attends to a lion and a panther. John does not attend to deer, lion or bison. A, B and C are allotted to Manish, John and Rocky respectively. A and E enclosures have one animal of the same species. C and D have the same pair of animals. The animals attended by Shailendra are-
(c) bear & lion
(c)
The data for Manish & John can be filled directly, similarly A, B, C directly from data given. The key after filling in these animals is that C and D have the same pair of animals, the only pair is deer & bison. Since Shalini doesn’t attend lion. Shailendra must attend the lion.
