Question
Statement : No ocean is a land. Some
lands are boundaries. All boundaries are banks. Conclusion : I. No ocean is a boundaries. II. All banks are lands. III. Some oceans are boundaries. In each question below are given three statements followed by three conclusions numbered I, II and III. You have to take the three given statements to be true even if they seem to be at variance with commonly known facts and then decide which of the given conclusions logically follows from the two given statements, disregarding commonly known facts.Solution
No ocean is a land (E) + some lands are boundaries (I) ⇒ some boundaries are not oceans (O*). Hence conclusion I will not follow but Conclusion I and III will make a complementary pair. Some lands are boundaries (I) + All boundaries are banks (A) ⇒ Some lands are banks (I) ⇒ Conversion ⇒ Some banks are lands (I). Hence Conclusion II will not follow.
