Question
Three statements are given followed by three
conclusions numbered I, II and III. Assuming the statements to be true, even if they seem to be at variance with commonly known facts, decide which of the conclusions logically follow(s) from the statements. Statements: No bottle is a cup. All bottle are plates. Some plates are spoons. Conclusions: I. All plates can never be cup. II. No bottle is spoon. III. At least some spoons are bottle.Solution
No bottle is a cup (E) → Conversion → No cup is a bottle (E) + All bottle are plates (A) → Some plates are not cup (O*) → Probable conclusion → All plates can never be cup (A). Hence conclusion I follows. All bottle are plates (A) + Some plates are spoons (I) → No conclusion. Hence neither conclusion II nor III follow.
