To calculate the value of raw materials consumed, we need to follow these steps:

Step 1: Determine the Opening Stock of Raw Materials. This is the stock at the beginning of the period. According to the information provided, the opening stock of raw materials is #20,000.

Step 2: Add any Purchases made during the year. In this case, raw materials purchased during the year amount to #18,000.

Step 3: Calculate the Closing Stock of Raw Materials. This is the stock at the end of the period, which is #500.

Step 4: Use the formula for the value of raw materials consumed:

Raw Materials Consumed = Opening Stock + Purchases - Closing Stock

Substitute the values:

#20,000 (Opening Stock) + #18,000 (Purchases) - #500 (Closing Stock) = #37,500

Therefore, the value of raw materials consumed is #37,500.
