Concept:A question based on supplied accounting data can only be answered when the complete set of figures is provided.
Without those figures, no accurate calculation can be made.
Explanation:The question states that certain information should be used to arrive at the correct amount.
However, no table, balances, trial balance, or any numerical data has actually been included with the question.
As a result, the required computation, such as net purchases, cost of goods sold, or gross profit, cannot be performed.
The possible answers given are
D37,800,
D20,000,
D19,800, and
D18,000.
There is simply no basis in the question to verify which, if any, of these amounts is correct.
Any attempt to pick one of the options would be a guess rather than a proper accounting solution.
Answer:Insufficient information — no valid option can be selected confidently.
