All-in cost per thousand bricks: Cost of 7000 bricks is Rs 5740. Luggage/transport to the site costs Rs 805. What is the total cost per 1000 bricks (including transport)?

Introduction / Context:
This is an average cost question: we combine purchase cost and transport cost to get a total, then convert to a per-1000 basis using the unitary method. Such problems appear frequently in procurement and construction cost estimation contexts.

Given Data / Assumptions:

• Material cost for 7000 bricks = Rs 5740
• Transport cost (luggage) = Rs 805
• Total bricks = 7000

Concept / Approach:
Total cost = purchase + transport. Then, cost per thousand = (total cost / total bricks) * 1000. Because 7000 is a multiple of 1000, division is simple.

Step-by-Step Solution:

Verification / Alternative check:
Reverse check: Rs 935 per thousand * 7 = Rs 6545 (matches total). The arithmetic is exact—no rounding needed.

Why Other Options Are Wrong:

• Rs. 900, Rs. 800, Rs. 750, Rs. 980: Do not equal 6545/7 exactly and reflect either under- or over-estimates.

Common Pitfalls:
Forgetting to include the transport cost, or computing per 100 instead of per 1000. Always convert using the correct scaling factor matching the asked unit basis.

Final Answer:
Rs. 935
