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: Only Years are Days. Few Years are Months. All Months are Weeks. Conclusions: I. Some Years are Weeks. II. No Day is Month. III. Some Days are Weeks.Solution
Few Years are Months (I) + All Months are Weeks (A) → Some Years are Weeks (I). Hence conclusion I follows. Only Years are Days → All Days are Years and Days can have negative relation with anyone. Hence conclusion II follows but conclusion III does not follow.
