I understand the three venn diagram but as per diagram-1 answer b is correct but if we use another diagram then we get another option also so how can we eliminate the another option or how can we take decision that which diagram is correct?

Conclusion should be true in diagram 1 and 2, but conclusion does not follow in diagram 1, so how conclusion 2 true ?

When one solves syllogism problems by Euler circles then a conclusion is true only if it is true in all possible diagrams i.e if a conclusion is not true in any one of Euler circle then it does not follow. Some watches are keys is not true in figure 1 so it does not follows.

According to figure 2 and 3 some watches are keys then why the conclusion 2 does not follow?

According to figure there may be chance to occur "some watches are keys" then why did it go wrong.

By Raval's notations statements are LL - K, KK - B, W - B now conclusions can be deduced at a glance.First conclusion B - L follows on linking B to L in KK - B and LL - K through common linking term K as it becomes double.Second conclusion W - K does not follow because common linking term B remains single on linking W -B and KK - B.Third conclusion KK - L does not follow because of absence of any common linking term.

Please I need some more techniques to solve these problems. I was confusing with venn diagrams. Can anyone explain me.
Sri said:   2 decades ago
According to the third figure some portion of watches are keys.

So, Conclusion 2 is also correct.
