. In the questions given below there are three
statements followed by three conclusions I, II and III. You have to take the three given statements to be true even if they seem to be at variance from commonly known facts. Read all the conclusions and then decide which of the given conclusions logically follows from the given statements disregarding commonly known facts. Statements: All planets are large. No large is small. All small are stars. Conclusion: I. No planets is small. II. Some stars are large. III. Some planets are stars.Solution
All planets are large (A) + No large is small (E) → No planets is small (E). Hence conclusion I follows. No large is small (E) + All small are stars (A) → Some stars are not large (O). Hence conclusion II does not follow. All planets are large (A) + No large is small (E) → No planets is small (E) + All small are stars (A) → No conclusion. Hence conclusion III does not follow.
