Discussion Forum : Logical Deduction - Section 1 (Q.No. 23)
Directions to Solve
In each question below are given two statements followed by two conclusions numbered I and II. 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 conclusion and then decide which of the given conclusions logically follows from the two given statements, disregarding commonly known facts.
Give answer:
- (A) If only conclusion I follows
- (B) If only conclusion II follows
- (C) If either I or II follows
- (D) If neither I nor II follows and
- (E) If both I and II follow.
23.
Statements: Some papers are pens. Angle is a paper.
Conclusions:
- Angle is not a pen.
- Angle is a pen.
Answer: Option
Explanation:
Since the middle term 'papers' is not distributed even once in the premises, no definite conclusion follows. However, I and II involve only the extreme terms and form a complementary pair. Thus, either I or II follows.

@All.
I need a clear illustration of complementary pairs in this logical deduction. Is it a general rule that when the E type and the I type propositions only form the complementary pairs?
Please tell me.
