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
Answer: Option
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.

The correct answer is E. Tigers are included in lions. The converse of first statement is "no lion is camel". If no lion is camel then it follows that "no camel can be tiger". In other words, conclusions 1 & 2 can't be false simultaneously. One of them has to follow for other to be false.

Correct answer is E. We can't assume that no camel is tiger. In the Venn diagram tiger is inside the lion. And no cow is lion. But some cows are camels that doesn't mean that remaining camels are not tiger. There is also possibility of some Camels as a lion. So either 1 or 2 can be true.

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?

Even it agree that the statement 2 is correct. Camel connection between tiger and cow is possible and cow still not touching tiger. The answer is wrong probably.

Sujit said:   7 years ago
No relation between lion and cow. Hence camel circle can be drawn by touching a tiger.

So, 2nd option seems to be correct.

I do agree with my other counterparts that the second statement is correct. Help me.

Dhwanit said:   8 years ago
I agree with the 3 rd option. So option c is correct.

Kavya said:   9 years ago
