Directions to Solve

In each of the following questions two statements are given and these statements are followed by two conclusions numbered (1) and (2). You have to take the given two statements to be true even if they seem to be at variance from commonly known facts. Read the conclusions and then decide which of the given conclusions logically follows from the two given statements, disregarding commonly known facts.

Give answer:

  • (A) If only (1) conclusion follows
  • (B) If only (2) conclusion follows
  • (C) If either (1) or (2) follows
  • (D) If neither (1) nor (2) follows and
  • (E) If both (1) and (2) follow.

11.

Statements: Some dogs are bats. Some bats are cats.

Conclusions:

  1. Some dogs are cats.
  2. Some cats are dogs.

Only (1) conclusion follows
Only (2) conclusion follows

We can see here it's a case of complementary pairs, if we look at it closely both the possibility are wrong but you see in the answer A option is there as either.

For example, take a set A={5, . }, B={5, . }, C={5, . } now when we say some A is B we can see that in set A and B we have one common element as 5 but the rest information is not know to us this leads two cases the remaining may either be same or either it may be entirely different but in case of syllogism we mark the answer on the basis of 100% true validity of the given information since we are given only a part of the information we can't conclude anything here comes the concept of complimentary pair. Please search google for more idea on complimentary pairs. Thank you and All the best.

I think here is either or option number is follow because as per rule of either & or protocol (both is wrong) & (similar both variable) so please confirm this equation.

I think the answer will be E.

Because some dogs are cats so in the second diagram some dogs are cats in the picture also some cats are dogs also it is there in the diagram some cars are dogs.

They have mentioned only some right it can be on or 100? So is this answer e.

The 2nd diagram shows the answer is e.

Please give the exact answer for this question.

Well. If the ones who are telling that opt D is right because of possibility case! why not consider the 2nd diagram as the real case, and the first one as a possibility? Then the answer will be different.

According to me, the 2nd diagram is correct!

In order to solve the same type of problem. We can conclude that. 1st draw all the possible venns and after that match the conclusions which satisfy both.

Now, I understand the given problem with the help of discussions.

Thank You all!

Unmesh said:   9 years ago
By looking at 2nd diagram we can say both are correct.

Thank you @Sneha.

How can we get solution without venn diagrams?

Please anyone give some simple logic in identifying the solution.
