In each of the questions below are given three statements followed by four conclusions numbered I, II, III and IV. You have to take the given statements to be true even if they seem to be variance from commonly known facts. Read the conclusion and then decide which of the given conclusions logically follows from the given statements disregarding commonly known facts.
Statements: All lions are ducks
No duck is horse
All horses are fruits
Conclusions:
I. No lion is horse
II. Some fruits are horses
III. Some ducks are lions
IV. Some lions are horses
We use elimination to find an exception to the generality of the conclusions. Thus we prove they are not implied. The diagram above satisfies all the statements but contradicts the conclusion IV. Since we found an exception, the conclusion is not true in "every" case. Thus it is not implied.
We can draw many scenarios that satisfy the statements using Venn diagrams and check for the validity of the conclusions. Conclusions I, II and III hold in every case. So, they are implied.
Since, this is not mentioned in any of the options, we choose (e) None of these as the answer.
