Correct Answer: Both conclusions III and IV follow


Solution : The possible Venn diagram according to the given statements is as follows –

Let's analyse the conclusions –
Conclusion (I): No curtain is a bedsheet – From the Venn diagram, it is evident that the circles representing curtains and bedsheets overlap and have some parts of their area in common. So, it can be concluded that some curtains are bedsheets. Thus, this conclusion does not follow.
Conclusion (II): No pillow is a curtain – From the Venn diagram, it is evident that the circles representing curtains and pillows overlap and have some parts of their area in common. So, it can be concluded that some pillows are curtains. Thus, this conclusion does not follow.
Conclusion (III): Some bedsheets are curtains – From the Venn diagram, it is evident that the circles representing curtains and bedsheets overlap and have some parts of their area in common. So, it can be concluded that some bedsheets are curtains. Thus, this conclusion follows.
Conclusion (IV): Some pillows are curtains – From the Venn diagram, it is evident that the circles representing curtains and pillows overlap and have some parts of their area in common. So, it can be concluded that some pillows are curtains. Thus, this conclusion follows.

So, both conclusions III and IV follow. Hence, the third option is correct.
