Question
Statement: Each dog is cat.   Only a
few cats are tigers. Some tigers are zebras.      Conclusion:      Some cats are zebras is a possibility. Only a few tigers are zebras is a possibility. Only cat is zebra a possibility.  In each of the question below are given some statements followed by some conclusions. You have to take the given statements to be true even if they seem to be at variance with commonly known facts. Read all the conclusions and then decide which of the given conclusions logically follows from the given statements, disregarding commonly known facts.ÂSolution
Some cats are tiger (I) + Some tiger are zebras (I) → Probable conclusion → Some cats may be zebras (I). Hence both conclusion I and III follows. Some tigers are zebras (I) → Probable conclusion → Some tigers may be zebras (I). Hence conclusion II follows. Alternate Method -
