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: All PR are OL All OL are RT Some RT are UE Conclusions: I. Some OL are UE. II. All PR are RT. III. Some RT are not PR.Solution
All OL are RT (A) + Some RT are UE (I) → No conclusion. Hence conclusion I does not follow. All PR are OL (A) + All OL are RT (A) → All PR are RT (A). Hence conclusion II follows but conclusion III does not follow.
