Statements: Some winters are summers.
All summers are springs. All springs are seasons. Conclusions: I. Some seasons are winters. II. All summers are seasons. III. Some seasons are not summers. 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 winters are summers (I) + All summers are spring(A)= Some winters are spring (I) + All spring are seasons (A)= Some winters are seasons (I) or Some seasons are winters.(I) Hence l follows. All summers are spring.(A)+All springs are seasons (A) = All summers are seasons (A). Hence, II follows. There is not any negative statement, so we cannot have any negative conclusion from it.
