Statement:\nMost dresses in that shop are expensive.\n\nWhich of the following is certainly true?

Difficulty: Easy

Correct Answer: Some dresses in that shop are expensive

Explanation:


Introduction / Context:
“Most” means “more than half.” From “Most dresses in that shop are expensive,” we must identify what must be true in every interpretation consistent with the statement.


Given Data / Assumptions:

  • Let the total number of dresses be N > 0.
  • “Most are expensive” ⇒ expensive > N/2.
  • No information about handloom category, exact counts, or whether all are expensive.


Concept / Approach:
Translate the quantifier “most” into set/number terms, then test each option for necessity vs. possibility.


Step-by-Step Solution:

• Option A: If more than half are expensive, then at least one is expensive. So “some are expensive” is certainly true.• Option B: “There are cheap dresses also” is possible but not necessary; “most” allows a minority to be cheap, but it could be zero if “most” were used loosely as “all but a few,” so we cannot assert existence.• Option C: Introduces “handloom” without basis; cannot be inferred.• Option D/E: Both are extreme (no cheap / all expensive) and contradict the flexibility of “most.”


Verification / Alternative check:
Example satisfying statement: Out of 100 dresses, 70 expensive, 30 cheap ⇒ A true; B true in this model but not necessary across all models.


Why Other Options Are Wrong:
They assert more than the premise (B, C, D, E) or add unsupported categories (C).


Common Pitfalls:
Misreading “most” as “all”; assuming the existence of the complementary set without proof.


Final Answer:
Some dresses in that shop are expensive.
