Explanation

• The first step is to calculate the total expenditure by adding the purchase price of the bricks to the transportation cost.
• Total Cost = Purchase Price (Rs. 5,740) + Transportation Cost (Rs. 805) = Rs. 6,545.
• This total cost of Rs. 6,545 is for 7,000 bricks.
• To find the cost per thousand bricks, we divide the total cost by 7 (since 7,000 bricks is 7 sets of 1,000 bricks).
• Calculation: Rs. 6,545 / 7 = Rs. 935.

Why Other Options Were Wrong

• Option B: This value represents the total cost for all 7,000 bricks.
• Option C: This value is the result of an incorrect calculation and does not correspond to any meaningful quantity derived from the problem's data.
• Option D: This is another incorrect calculation that does not reflect the cost per thousand bricks.

How to Approach the Question

• Step 1: Read the question carefully to identify all given values. Note the purchase cost (Rs. 5,740), transportation cost (Rs. 805), and total quantity (7,000 bricks).
• Step 2: Determine the 'overall cost' by adding all expenses together. Total Cost = 5,740 + 805 = Rs. 6,545.
• Step 3: Understand what the question is asking for. It requires the 'cost per thousand bricks', not the cost per single brick or the total cost.
• Step 4: Set up the calculation to find the cost for 1,000 bricks. Since the total cost of Rs. 6,545 is for 7,000 bricks, divide the total cost by 7.
• Step 5: Perform the division: 6,545 ÷ 7 = 935.
• Step 6: Compare your result with the given options and select the matching one, which is Rs. 935.00.
