If an exam question says commission is on net profit and another adjustment is to be allowed first what is the usual caution?

Correct answer: Read the order of instruction before deciding commission base

The direct answer is option A: read the order of the instructions before deciding the commission base. In partnership problems, words such as 'on net profit', 'before commission', 'after commission', 'after salary', or 'after other adjustments' control the calculation. First identify the profit figure to which the stated percentage applies, then make the adjustments in the specified order. Option A is correct because the sequence can change the base and therefore the answer. Option B is wrong because commission on net profit is not automatically commission on gross profit. Option C is wrong because commission is not zero unless the question says so. Option D is wrong because commission is an appropriation or expense-related adjustment, not a partner's drawings. A common trap is calculating a percentage before reading whether another adjustment must be made first. Exam cue: underline 'before' and 'after' before calculating.
