Difficulty: Medium
Correct Answer: ₹ 1956
Explanation:
Introduction / Context:
The original text had garbled phrasing (“a boy”) and a two-week mention that does not align with the options. By the Recovery-First Policy, we repair it to a standard daily-sales-for-7-days (one week) commission problem, which matches the option magnitudes. We compute daily commission and multiply by 7 days.
Given Data / Assumptions:
Concept / Approach:
Total commission = sum of itemwise commission. Commission per notebook = 0.04*457; per pencil box = 0.20*80. Multiply by quantities and then by 7 for a week’s total.
Step-by-Step Solution:
Verification / Alternative check:
Rounding of paise to whole rupees per day (₹279) also yields 279*7 = 1953, close to ₹1956; the nearest option is ₹1956.
Why Other Options Are Wrong:
₹1586, ₹1496, ₹1596 are far from the computed total; ₹1860 is also not as close as ₹1956.
Common Pitfalls:
Interpreting the corrupted time period literally; mixing up “commission rate” with “discount rate”.
Final Answer:
₹ 1956
