Question
Statements : All scores are marks. All exams are
marks. No mark is an attempt. Conclusions : I. All exams being scores is a possibility. II. Some attempts are scores. III. Some exams are attempts. In each of the questions below are given three statements followed by three conclusions numbered I, II and III. 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 given conclusions logically follows from the given statements disregarding commonly known facts.Solution
All exams are marks(A) + Some marks are scores(I) ⇒ Probable conclusion ⇒ All exams may be scores(A). Hence, conclusion I follows. All scores are marks(A) + No mark is an attempt(E) ⇒ No score is a attempt(E) ⇒ conversion ⇒ Some attempts are not scores(O). Hence, conclusion II does not follow. All exams are scores (A) + Some scores are marks (I) ⇒ No conclusion. Hence, conclusion III does not follow.
