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

The word commomn in both the statements should not come in the conclusion na, then how the answer will be E.

Actually the answer is based on "convergence" formula of both. It is true in both cases of venn diagram. So both 1 and 2 folllows.

Firstly.
If we go according to the distributed and undistributed pattern. Since the middle term "pens" isnt distributed even once.
So the statements donot hav any conclusion.
Secondly,
I agree with anvitha. The word "pens", since common should not come in the conclusion.

If we go according to the distributed and undistributed pattern.
Only Conclusion 2 follows.
Because middle term "pencils" is distributed from statement2.

1. "Some pens are pencils" cannot follow since in the syllogism, the middle term (pen)is not distributed. This is shown by the fig.1 given. in deductive arguments conclusions that are ceratain can only be considered.
2. "Some pens are papers" follows from "Some papers are pens" using the rule of conversion.
Hence the ansswer is B; "Only (2) conclusion follows"
If possible, use Venn diagrams or Syllogistic rules to solve such problems.
The diagrams of the type given above may not exhaust all possibilities and hence can be erroneous.
Even in using such diagrams, look for the possibility of rejecting the conclusion rather than accepting it. If there is any possibility to reject, reject it.
In addition, one may use the rules of opposition (contradictory, contrary, sub-contrary and sub-alternation) and eduction such as conversion obversion contraposition and inversion to attempt all such problems.

1. "Some pens are pencils" cannot follow since in the syllogism, the middle term is not distributed. This is shown by the fig.1 given. In deductive arguments conclusions that are certain can only be considered.
2. "Some pens are papers" follows using the rule of conversion from "Some papers are pens".
Hence the answer is B "Only (2) conclusion follows"

According to the rule 3 of syllogism, the middle term should be distributed. Here the middle term is not distributed.
