In this type of questions some problematic situations are provided you have to analyse the situation and give the logical correct solution for the problem.
If ALL PENS ARE BLUE and SOME BLUE ARE INK, which of the following is always true?
Show answer & explanation
Correct answer: B
Explanation
The correct answer is some blue pens.
Statement 1: "All pens are blue"
This means that all of the pens fall within the 'blue' circle.
When all the pens are within the blue circle, some portion of the blue part must be near the pen. Therefore, the conclusion "Some blue are pens" will always be true.
Statement 2: "Some blue are ink"
This means that the 'blue' and 'ink' circles intersect slightly.
But whether that portion of the ink will touch the pen or not is not certain (it may or may not).
