Statements:All trains are buses. No room is bus. All boats are rooms.Conclusions:I. No boat is train.II. No bus is boat.III. No train is room.Which of the following is/are most appropriate in the above scenario?
Correct answer: C. I, II and III
- A. Only I and III
- B. Only I and II
- C. I, II and III
- D. Only II and III
Explanation
Let's check each conclusion:I. No boat is train. This follows.All boats are rooms.No room is a bus.All trains are buses (so trains are buses, but boats are rooms, and rooms and buses are completely separate).Hence, boats (rooms) cannot be trains (buses).II. No bus is boat. This follows.Boats are rooms, and no room is a bus.So, no bus can be a boat.III. No train is room. This follows.Trains are buses, and no room is a bus.So trains cannot be rooms.Final Answer: All three conclusions (I, II, and III) follow.

About Logical Problems
Logical problems present several conditions about people, objects, events or choices and require their possible arrangements to be tested. They cover constraint-based reasoning, rankings, matching, grouping, scheduling and elimination, with attention to the difference between a complete solution and a possibility that merely satisfies one condition.
