Question
Statements: Only a few hands are ears Some
ears are eyes All eyes are arms Conclusions: I. No arm is a hand II. Some ears are arms III. All ear is being hand is a possibility In each of the questions 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 from 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.Solution
Some hands are ears (I) + Some ears are eyes (I) → No conclusion. Hence conclusion I does not follow. Some ears are eyes (I) + All eyes are arms (A) → Some ears are arms (I). Hence conclusion II follows. Only a few hands are ears→ Probable conclusion → All ear may be hand (A). Hence conclusion III follows.
