Question
Statements: Some printers are carbons. No carbon
is a graphite. No diamond is printer. Conclusions:I. All printers are diamond. II. Some diamonds are carbons. In each question below are given three statements followed by two conclusions numbered I and II. You have to take the given statements to be true even if they seem to be at variance with commonly known facts. Read all the conclusions and then decide which of the given conclusion logically follows from the given statements, disregarding commonly known facts. Give answer :Solution
No diamond is printer(E) ⇒ conversion ⇒ No printer is a diamond (E). Hence conclusion I does not follow. No diamond is printer (E) + Some printers are carbons (I) ⇒ Some carbons are not diamond (O*). Hence conclusion II does not follow. Alternate method:
