Question
Statement: Only a few scale are
erasers. No eraser is a pen. Only colours are pens. Conclusion: Some erasers can be colours. All colours being scale is a possibility. All scale being colours is 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.Solution
No eraser is a pen (E) + All pens are colours (A) → Some colours are not erasers (O*) → Probable conclusion → Some erasers can be colours (I). Hence conclusion I follows. Some scale are erasers (I) + No eraser is a pen (E) → Some scale are not pens (O) + Only colours are pens → No conclusion. Hence neither conclusion II nor III follow. Alternate Method -
