Correct Answer: Only conclusions I and II follow
Solution : The possible Venn diagram according to the given statements is as follows –
Let's analyse the conclusions – Conclusion (I): Some coolers are machines – From the Venn diagram, the circle of the cooler intersects the circle of the machine and has a common area between them. Therefore, this conclusion is true. Conclusion (I): Some robots are machines – From the Venn diagram, the circle of the robot intersects the circle of the machine and has a common area between them. Therefore, this conclusion is true. Conclusion (I): No robot is a microwave – From the Venn diagram, there is no negative relation between a robot and a microwave. Therefore, this conclusion is false.
So, only conclusions I and II follow. Hence, the third option is correct.
