1. The problem is to find a subset of items from an Excel file whose total value sums to exactly 12121624.47, with the constraint that quantities can be reduced but not increased. 2. Since the file is not yet uploaded, I cannot analyze the data or perform calculations. 3. Once you upload the Excel file, I will help you identify the items and quantities that sum to the target amount. 4. This is a variation of the subset sum problem with quantity constraints, which can be solved using optimization or integer programming techniques. 5. Please upload the file to proceed.
