Market share claim on radio sets: Interpreting the assertion that brand X has the largest sales in India and identifying the necessary implicit assumption

Given data

• Statement: Of all radio sets manufactured in India, brand X has the largest sale.
• Assumption I: Sales figures of all radio sets in India are known.
• Assumption II: No other brand is manufactured in as large a quantity as brand X.

Concept/Approach

To assert 'largest sale,' comparative sales information is required. Manufacturing volume is a different metric and is not needed to support a sales-based superlative.

Step-by-Step reasoning
1) Knowing who sells the most implies access to comparative sales data ⇒ I is implicit.2) Production volume could be lower or higher yet sales could still be largest due to demand; II is not implied.

Verification/Alternative

The claim would stand even if another brand produced more units but sold fewer (inventory unsold), confirming II is irrelevant.

Common pitfalls

• Confusing manufacturing output with actual sales.

Final Answer
Only assumption I is implicit.
