Difficulty: Easy
Correct Answer: 126
Explanation:
Introduction / Context:
This is a straightforward unit-rate calculation: total items produced divided by total worker-hours yields a per-worker per-hour productivity figure.
Given Data / Assumptions:
Concept / Approach:
Average output per weaver per hour = (total shawls) / (total weaver-hours) = 6594 / (314 * 1/6).
Step-by-Step Solution:
Total weaver-hours = 314 * (1/6) = 314/6 hours. Average rate per weaver per hour = 6594 / (314/6) = 6594 * 6 / 314. Compute 6594 * 6 = 39564. Now 39564 / 314 = 126. Hence, each weaver averages 126 shawls per hour.
Verification / Alternative check:
Multiply back: 126 shawls/hour * 314 weavers * (1/6) hour = 126 * 314 / 6 = 126 * 52.333… = 6594. Matches the given total.
Why Other Options Are Wrong:
42, 21, 84, 102 are lower than the computed exact average; they arise from dividing by the number of weavers or time incorrectly.
Common Pitfalls:
Forgetting to multiply by 6 when converting 10 minutes (1/6 hour) to hourly rate; dividing by workers before accounting for time properly.
Final Answer:
126
