GPSC (Gujarat) - MCQ Practice Questions

Each letter shifts by its position: G(+0), A(-1), R(+3), D(-2), E(+5), N(-6). Apply same pattern to FLOWERS.

Each letter is replaced by the letter that is 9 positions back. M→N, O→L, B→D, I→B, L→J, E→D.

The ratio of ages changes every year and will never be the same again as initially it was 24:18 or 4:3.

This is a pure text question involving basic logic and set relationships.

We are given two premises:

1. All roses are flowers.

2. Some flowers are red.

We need to determine what must be true — that is, what is guaranteed to follow from these premises alone, regardless of any other assumptions.

Option A ("All roses are red") does not have to be true. The red flowers mentioned in premise 2 could be tulips or daisies — none of them need to be roses.

Option B ("Some roses are red") also does not have to be true, for the same reason: the red flowers could be entirely non-rose flowers, leaving all roses non-red.

Option C ("No roses are red") is not guaranteed either — it is possible that some roses are red, so this cannot be asserted as a necessary truth.

Option D ("Some flowers are not red") must be true. Here is why: premise 2 tells us only that *some* flowers are red, which means the statement does not cover all flowers. Since roses are flowers (by premise 1), and roses need not be red (as established above), there exists at least a logical possibility — in fact a necessity given the structure — that some flowers fall outside the "red" category. More precisely, "some flowers are red" is not the same as "all flowers are red," so it directly implies that the set of flowers is not entirely red, meaning some flowers are not red.

Therefore, the answer that must be true based solely on the given premises is D: Some flowers are not red.

Letters jump by 3 (A→D→G→J), numbers increase by 2 (2→4→6→8), last letter shifts by 1 each time (B→E→F→G). So J8G

If all A are B and some B are C, then it's possible some A are C, but not guaranteed. Therefore, 'Some A may be C' is the logically consistent statement.
