Question
Some mobiles may not be papers. Some dusters are not
calculators In the given question, a set of conclusions is given. There are five options comprising of three or more statements. You need to choose the option that contains the set of statements from which the given conclusions logically follow.Solution
Some mobiles are calculators(I) + All calculators are papers(A) ⇒ Some mobiles are papers(I) ⇒ Probable conclusion ⇒ Some mobiles may not be papers(O). All calculators are papers (A) + No paper is a duster(E) ⇒ No calculator is a duster (E) ⇒ conversion ⇒ Some dusters are not calculators(O). By elimination method - By option 1, No + no = no definite conclusion can be drawn between duster and calculator. Hence it is eliminated. By option 2, No + some = Some calculators are not duster. But we can’t conclude that some dusters are not calculators. Hence it is eliminated. By option 3, few + no = Some mobiles are not papers. So possibility can’t be drawn. Hence it is eliminated. By option 4, the conclusion can be drawn. Hence answer is 4.
