Question
Statement: Only yellow is red. Some
blacks are yellows. Only a few greens are blacks. Conclusions: I. Some greens being reds is a possibility. II. All yellows can be greens. III. All Blacks can be yellows. 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.Solution
Only yellow is red means All reds are yellows and in this case red will not have any relation to anyone. Hence conclusion I does not follow. Some greens are blacks (I) + Some blacks are yellows (I) → No conclusion. Hence conclusion II does not follow. Some blacks are yellows (I) → Probable conclusion → All blacks can be yellows (A). Hence conclusion III follows. Alternate Method -
