Read the given statements and conclusions carefully and decide which of the conclusions logically follow(s) from the statements.
Statements:
i. Some printers are laser.
ii. Some printers are inkjet.
iii. No inkjet is a laser.
Conclusions:
i. Some inkjet are laser.
ii. Some laser are inkjet.
Some laser are not inkjet.

Correct option is D

From the statement following Venn diagram can be –

Conclusions:
i. Some inkjet are laser.
· In syllogistic logic, when a universal negative statement like "No inkjet is a laser" is given, it implies that the two sets (inkjets and lasers) are completely separate.
ii. Some laser are inkjet.
· Any conclusion that suggests an overlap between these two sets (like Conclusions i and ii) cannot be true.
iii. Some laser are not inkjet.
· A conclusion that states "Some lasers are not inkjets" is valid because it aligns with the fact that there is no overlap; in fact, all lasers are not inkjets, so saying some is correct.
Correct answer is (d) Only (iii) follows.
