Question

In each question below are given two statements followed by two conclusions numbered I and II. You have to take the two given statements to be true even if they seem to be at variance with commonly known facts and then decide which of the given conclusions logically follows from the two given statements, disregarding commonly known facts. Give Answer:

Statements: All red are yellow.

                             All yellow are pink.

Conclusions:   I. Some pink are red.

        II. No yellow is a pink.

A If only conclusion I follows Correct Answer Incorrect Answer
B If only conclusion II follows Correct Answer Incorrect Answer
C If either I or II follows Correct Answer Incorrect Answer
D If neither I nor II follows Correct Answer Incorrect Answer
E If both conclusions I and II follow Correct Answer Incorrect Answer

Solution

All red are yellow (A) + All yellow are pink. (A)= All red are pink (A) ⇒ conversion ⇒ Some pink are red (I). Hence, conclusion I will follow. Both the statements are positive statements and conclusion II is negative and we know that negative definite conclusions cannot be drawn from the positive statements. Hence, conclusion II will not follow.
