Sales revenue/ gross profit= % margin.
so calculate profit like below
Sales revenue
-Cogm
= gross profit
(cogm or cos = opening stock+ purchases)
the question does not address what to do, so assuming that one needs to find out what is the profit margin on actual price (normal price isn’t already analysed above), substitute sales revenue by actual price data for P,Q,R individually. All the best.
