Question
Statements:Some whys are where’s. All
when’s are whys. All where’s are who’s. Conclusions:I. Some who’s are whys. II. All where’s are when’s. III. Some where’s are not when’s. 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
Some whys are where (I) + All where are who’s (A) = Some whys are who’s.(I) ⇒ conversion ⇒ Some who’s are whys.(I) Hence, conclusion I will follow. A + I = No conclusion. Hence, neither conclusion II nor III follows. However, Conclusion II and III make a complementary pair, hence, either conclusion II or III follows. Alternative method:
