Question

Read the given statements and conclusions carefully. Assuming that the information given in the statements is true, even if it appears to be at variance with commonly known facts, decide which of the given conclusions logically follow(s) from the statements.

Statement:

All Dog are Rat.

All Rat are Cat.

Some Dog are Camel.

Conclusions:

I. Some Rat are Camel.

II. Some Cat are not Dogs.

III. All Cat are Camel.

A Only conclusion I follows Correct Answer Incorrect Answer
B Only conclusion I and II follows Correct Answer Incorrect Answer
C Only conclusion II and III follows Correct Answer Incorrect Answer
D Only conclusion I and III follows Correct Answer Incorrect Answer

Solution

Some Dog are Camel (I) → Conversion → Some Camel are Dog (I)  + All Dog are Rat (A) → Some Camel are Rat (I) → Conversion → Some Rat are Camel (I). Hence conclusion I follows. All Dog are Rat (A) + All Rat are Cat (A) → All Dog are Cat (A) → Conversion → Some Cat are not Dog (I). Hence conclusion II does not follows. Some Cat are not Dog (I) + Some Dog are Camel (I) → No conclusion. Hence conclusion III does not follows.
