Discussion Forum : Logical Problems - Type 4 (Q.No. 10)
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: | Some pens don't write. |
| Fact 2: | All blue pens write. |
| Fact 3: | Some writing utensils are pens. |
| I: | Some writing utensils don't write. |
| II: | Some writing utensils are blue. |
| III: | Some blue writing utensils don't write. |
Answer: Option
Explanation:
Since some pens don't write, some writing utensils don't write (statement I). Since there are blue pens and since pens are writing utensils, some writing utensils are blue (statement II). There is not enough information to support statement III.

The problem here is whether PENS are within WRITING UTENSILS.
1) If ALL "pens" are within "writing utensils" then B.
2) If SOME "pens" are within "writing utensils" then D.
Based on the given facts (without external knowledge) it is not certain that ALL pens are writing utensils (maybe some pens are for drawing or whatever). So I would say the 2nd rule applies, therefore the correct statement is D.

I think option D is correct. Because it is not given that all writing utilities are pen.
Some writing utilities are pen. But which type of pen? They all can be blue. In case all writing utilities writes.
So option D is correct.

Option D is correct, as:
1- Some pens who don't write need not be a writing utensil. Hence statement 1 is incorrect.
2- Writing utensils can be of a color other than blue. No where is ti mentioned blue pens are utensils. Hence statement 2 is also incorrect.
3- Statement 3 is anyways incorrect as it says some blue pen can't write. Hence it is not possible as per the given fact.
Thus none of the statements is true and therefore option D is correct!
