Maam if the scenario doesn’t talk about sales tax and discounts on purchases/expenses at all can we still just assume it exists, and state that following as SP for purchases/expenses ?
“recalculate the discounts and sales tax applied for s ample of purchase invoices to confirm accuracy” or it would be seen as a general procedure and discredited?
Sounds like invention/speculation and not answering the question in the context of the specifics of the given scenario unless there is mention of discounts/sales tax.
