Question
In this question, three statements are given, followed
by two conclusions numbered I and II. Assuming the statements to be true, even if they seem to be at variance with commonly known facts, decide which of the conclusions logically follows/follow from the statements. Statements: All cars are trains. All trains are scooters. Some scooters are cycles. Conclusions: I. All cycles are cars. II. Some cycles are trains.Solution
All cars are trains (A) + All trains are scooters (A) → All cars are scooters (A) + Some scooters are cycles (I) → No conclusion. Hence conclusion I does not follow. All trains are scooters (A) + Some scooters are cycles(I) → No conclusion. Hence conclusion II does not follow.
