Brick consignment costing — include carriage 7000 bricks cost Rs 5740 and carriage (luggage) to site costs Rs 805. What is the total cost per thousand bricks?

Introduction / Context:
In materials costing (common in civil works or procurement), you must include both purchase price and carriage to compute the effective rate per thousand units. This problem asks for a combined unit rate.

Given Data / Assumptions:

• Cost of 7000 bricks = Rs 5740.
• Carriage (luggage) = Rs 805.
• Find cost per 1000 bricks including carriage.

Concept / Approach:
Add the two cost components, then divide by the number of thousand-brick lots in 7000. Finally, compute the per-thousand rate.

Step-by-Step Solution:
Total effective cost = 5740 + 805 = 6545.Quantity = 7000 bricks = 7 thousands.Rate per thousand = 6545 / 7 = 935.

Verification / Alternative check:
Unit cost per brick = 6545 / 7000 ≈ 0.935; multiply by 1000 ⇒ 935 (consistent).

Why Other Options Are Wrong:
800 and 750 ignore carriage or mis-divide; 900 and 970 do not match total/quantity arithmetic.

Common Pitfalls:
Forgetting to add carriage or dividing by 1000 rather than the number of thousand-brick groups (7).

Final Answer:
Rs 935
