Question

In this question, three statements are given, followed by three conclusions numbered I, II and III. Assuming the statements to be true, even if they seem to be at variance with commonly known facts, decide which of the conclusion(s) logically follows/follow from the statements.
Statements:
I. All pants are shirts.
II. All shirts are jackets.
III. Some jackets are sweaters.
Conclusions:
I. Some jackets are pants.
II. Some sweaters are shirts.
III. No pant is a sweater.

None of conclusions I, II or III follows.

Both conclusions I and II follow

Both conclusions II and III follow.

Only conclusion I follows.

Solution

Correct option is D

Statements:
I. All pants are shirts.
II. All shirts are jackets.
III. Some jackets are sweaters.

From the given statements Venn diagram will be:

Conclusions:

I. Some jackets are pants. (Follows, Since all pants are shirts and all shirts are jackets, it means all pants are jackets too.)
II. Some sweaters are shirts. (Not Follows, Since not all jackets are shirts (some sweaters may not be shirts), there is no definite information that some sweaters are shirts.)
III. No pant is a sweater. (Not Follows, There is no information given about any relation or non-relation between pants and sweaters.)

So, Only conclusion I follows.

Thus, correct option is (d).
