Discussion Forum : Logical Problems - Type 4 (Q.No. 4)
Directions to Solve
The logic problems in this set present you with three true statements: Fact 1, Fact 2, and Fact 3. Then, you are given three more statements (labeled I, II, and III), and you must determine which of these, if any, is also a fact. One or two of the statements could be true; all of the statements could be true; or none of the statements could be true. Choose your answer based solely on the information given in the first three facts.

| Fact 1: | All chickens are birds. |
| Fact 2: | Some chickens are hens. |
| Fact 3: | Female birds lay eggs. |
| I: | All birds lay eggs. |
| II: | Some Hens are birds. |
| III: | Some chickens are not hens. |
Answer: Option
Explanation:
The first statement cannot be true because only female birds lay eggs. Statement II is true because some hens are chickens and all chickens are birds. Statement III is also true because if only some chickens are hens, then some must not be hens.

I think option 3 is only the fact because "some chickens are hens" and we know that"all chickens are birds " so all hens are birds.

I think that the 2nd statement is not true as they said some hens are chickens and all chickens are birds which means all hens are birds.
Correct me, if I am wrong.

"Some chickens are not hens" can not be implied to be correct or incorrect. Because we only know that "some chickens are hens" but we have no idea about rest of the chickens. Hence only conclusion II is correct.

Earlier you talked about affirmative and negative sentences.
As in this question no negative sentence hence option 3 is wrong.
Answer should be option 2 only.

Option B is correct.
You cannot convert some to some not because if you did that means From a single statement you are concluding many.
For ex: if you say all chickens are hens, we can also say that some chicken are hens which is true and it's converse some hens are chickens is also true.
Now,
According to your rule, some chicken are hens can also be said some chicken are not hens which is not possible since you cannot converse it plus there will be number of conclusions from a single statement.
