Question
In the question below there are three statements
followed by two conclusions I and II. You have to take the three given statements to be true even if they seem to be at variance from commonly known facts and then decide which of the given conclusions logically follows from the three statements disregarding commonly known facts . Statements: All Treasure are Jewel. Some Jewel are Gold. Only Gold are Silver. Conclusions: I. Some Treasure are not Silver. II. All Gold can never be Jewel.Solution
Only Gold are Silver β All Silver are Gold and Gold can have negative relation with anyone. Hence conclusion I and II follow.
