Profit and Loss — A calculator sells at ₹ 250 each “including” a profit of 14% (per unit). If 7 calculators are sold per day for 19 days, compute the total profit earned.

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:

Verification / 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
