Question
In the following question, some conclusions are given
and some statements are given you have to take the given conclusions to be true even if they seem to be at variance with commonly known facts and then decide from which of the statements given in options (A), (B), (C), (D) and (E) which make the conclusions given in the statement definitely true. Conclusions: No rubber is a tree. All trees being banyan is a possibility. Statements: 1: All flowers are trees. No tree is a herb. All rubber are trees. All herbs are banyan. 2: Some flowers are trees. No tree is a Banyan. All rubber are herbs. All herbs are banyan. 3: Some flowers are trees. No tree is a herb. All rubber are trees. All herbs are banyan. 4: All flowers are trees. No tree is a Banyan. All rubber are herbs. All herbs are banyan. 5: All flowers are trees. No tree is a herb. All rubber are herbs. All herbs are banyan.Solution
From Statement 5: All rubber are herbs (A) + No tree is a herb (E) → Conversion → No herb is a tree (E) → No rubber is a tree (E). No tree is a herb (E) + All herbs are banyan (A) → Some banyan are not tree (O*) → Probable conclusion → All tree may be banyan (I).
