Question

In the following question, some statements followed by conclusions are given. Read all the conclusions and decide which logically follows the statements. Statements:

• No tap is nozzle.
• Some valves are taps.

Conclusions:

• All nozzles are valves.
• All valves are nozzles.

• A. Only conclusion I follows
• B. Only conclusion II follows
• C. Neither conclusion I nor II follows
• D. Both conclusions follow

Hint:

When evaluating logical conclusions, carefully analyze the relationship and overlapping sets described in the statements. Draw Venn diagrams if needed to visualize.

Answer 1

The Correct Option is C

Step 1: Analyze statements
- Statement 1: "No tap is nozzle" means taps and nozzles are completely different groups.
- Statement 2: "Some valves are taps" means valves and taps overlap partially.
Step 2: Analyze conclusions
- Conclusion I: "All nozzles are valves" — Cannot be true because no taps are nozzles, and valves only overlap with taps, so no conclusion about nozzles and valves can be drawn.
- Conclusion II: "All valves are nozzles" — Cannot be true as valves are only partially related to taps, and taps are distinct from nozzles.
Hence, neither conclusion logically follows.
