When the terms are more than two we apply some another method. First of all the basic Venn diagram of the statement that totally satisfies it. Then we enlarge it as all L, K, B in one circle and another by BW. So according to this, 1 and 3 should be true.

I am not sure weather it is correct or not. But what I have understood observing all the problems. We use third possibility diagram when all the statements are having only SOME without having ALL. We use only first Diagram when one of the statements Starts with ALL.
Vinod said:   9 years ago
Yes, conclusion 2 is correct.

In my opinion, the answer is D - as 1 and 3 is correct. The argument for 1 to be correct is well stated above, however, 3 is also correct for the following reason:

If all locks are keys ( locks = keys), then all keys are locks as x=y then y=x. The diagram does not take this into consideration.

As per the 2nd figure, why some watches are not keys?

I think option B is the right answer.
Santanu said:   10 years ago
According to me, both the conclusions 1 and 2 are correct.

Yeah. All possible diagrams should satisfy the conclusion. For the conclusion to be true.
