Arithmetic is asked in objective competitive exams. II. Fast Objective Arithmetic is the only Arithmetic book by Arihant. III. People read newspaper X. Choose the option that identifies the implicit assumption or assumptions.

Introduction / Context:
Assumptions are unstated premises that must hold for the statement to make sense. We test which claims the advertisement relies on to be persuasive.

Given Data / Assumptions:

• The ad targets exam aspirants through a newspaper channel.
• It claims the book will help in objective competitive exams.
• It does not claim exclusivity among Arihant titles.

Concept / Approach:
Identify what must be true for the ad to be meaningful to its audience, not what would merely strengthen it.

Step-by-Step Solution:
I: Implicit. If arithmetic were not asked in such exams, the promise would be irrelevant.II: Not implicit. The ad works even if Arihant publishes multiple arithmetic books.III: Implicit. For the ad to be worth placing in newspaper X, the advertiser assumes readers will see it.

Verification / Alternative check:
Ads routinely rely on audience reach assumptions (III) and topical relevance (I).

Why Other Options Are Wrong:
Options with II impute exclusivity that the text does not require; singletons omit the other necessary assumption.

Common Pitfalls:
Confusing strengthening with necessity.

Final Answer:
I and III are implicit
