Directions to Solve

In each of the questions below are given three statements followed by three conclusions numbered I, II and III, You have to take the given statements to be true even if they seem to be at variance from the commonly known facts. Read all the conclusions and then decide which of the given conclusions logically follows from the given statements disregarding commonly known facts.

13.

Statements: All tigers are lions. No cow is lion. Some camels are cows.

Conclusions:

1. Some lions are camels.
2. No camel- is tiger.
3. Some tigers are cows.

None follows
Only I follows
Only II follows
Only III follows
Either I or II follows
Explanation:

All tigers are lions. No cow is lion.

Since both the premises are universal and one premise is negative, the conclusion must be universal negative (E-type) and shouldn't contain the middle term. So, it follows that 'No tiger is cow'.

Some camels are cows. No cow is lion.

Since one premise is particular and the other negative, the conclusion must be particular negative (O-type) and should not contain the middle term. So, it follows that 'Some camels are not lions'. Some camels are cows. No tiger is cow.

Since one premise is particular and the other negative, the conclusion must be particular negative (O-type) and should not contain the middle term. So, it follows that 'Some camels are not tigers'.

@Milan: "Some tigers are cows", this statement is absolutely wrong. In Venn Diagram, Tiger is mapped inside the Lion, and when dey mentioned here that No cow is lion then how its possible that. That's why this statement is wrong.

"no camel is tiger" and "Some lions are camels", it may be or may not be true through the Venn Diagram.

Some lions are camels.
Some tigers are cows.
Both the statements are false.

And no camel is tiger seems to be true?

How is it possible that statement is wrong?

Can you explain how it happens?
