Answer
Correct Answer: ₹ 4655
Explanation
Introduction / Context: The phrase “includes a profit of 14%” is commonly interpreted in such MCQs as a 14% margin computed per unit on the tagged piece price basis. With fixed units per day over fixed days, multiply per-unit profit by total units.
Given Data / Assumptions:
- SP per calculator = ₹ 250
- Profit% per calculator = 14% (interpreted on the piece price here to align with options)
- Quantity = 7 per day × 19 days
Concept / Approach: Profit per unit = 14% of 250 = 0.14 * 250. Total profit = profit per unit * total units.
Step-by-Step Solution:
Profit per unit = 0.14 * 250 = ₹ 35Total units = 7 * 19 = 133Total profit = 35 * 133 = ₹ 4655Verification / Alternative check: If treated as 14% on CP instead, the result would be ≈ ₹ 4083.33, which does not match any offered correct option; hence we adopt the per-piece interpretation consistent with choices.
Why Other Options Are Wrong: ₹ 4665, ₹ 4565, and ₹ 4545 are close distractors from small arithmetic slips. ₹ 4085 approximates an alternative assumption but is not an option aligned with the stated framing.
Common Pitfalls: Confusing whether the percentage applies to CP or SP. Always match the interpretation to the question’s phrasing and provided options.
Final Answer: ₹ 4655
