Question

Two 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 conclusions logically follow(s) from the statements.
Statements:
1. Some caps are shirts.
2. Some shirts are coats.
Conclusions:
I. No coat is cap.
II. No coat is shirt.
III. Some coats are caps.

• A. Either conclusion II or III follow.
• B. Conclusions II and III follow.
• C. Either conclusion I or III follow.
• D. Conclusions I and II follow.

Answer 1

Answer:

C. Either conclusion I or III follow.

I. No coat is cap – It is not a definite case, hence false.

II. No coat is shirt – It is not a definite case, hence false.

III. Some coats are caps – it is not a definite case, hence false.

Since both conclusion I and III have complementary pairs so, either conclusion I or III follow.
