Statement–Assumption — Notice in a sweet shop: “While weighing sweets, we do not include the weight of the box used to carry the sweets.” Assumptions: I. The cost price of a box is not less than the cost of sweets per gram. II. Customers prefer to pay only for the weight of the sweets they buy.
Correct Answer: if only assumption II is implicit.
Introduction / Context:The notice clarifies pricing fairness: pay for sweets, not packaging. We must spot the required customer-belief premise.
Given Data / Assumptions:
- Sweets are sold by weight; boxes add tare weight.
- Fair practice removes tare from net weight billed.
Concept / Approach:For the notice to matter, the shop presumes customers value and expect being charged only for edible content (II). Assumption I about relative cost prices is irrelevant; even if boxes are cheap, fairness still dictates tare exclusion. The practice is anchored in consumer preference for transparent weighing, not in comparative cost metrics.
Step-by-Step Solution:1) II is necessary—otherwise, the notice would not reassure or influence customer satisfaction.2) I is unnecessary—box cost vs sweet cost does not determine the weighing policy.
Verification / Alternative check:Retail weighing standards (net vs gross) emphasize consumer fairness over component cost comparisons.
Why Other Options Are Wrong:I-only and both import an irrelevant premise; “neither” ignores the fairness expectation.
Common Pitfalls:Confusing pricing ethics (net weight) with cost accounting of packaging.
Final Answer:if only assumption II is implicit.
