The correct answer to the question "A company's Q1 financial report shows the following for its three divisions: Division A had $500M revenue and $100M profit. Division B had $750M revenue and $120M profit. Division C had $400M revenue and $84M profit. Which division had the highest profit margin (Profit/Revenue)?" is Option C: Division C.

The other options — A) Division A, B) Division B, D) Divisions A and C had the same highest margin. — are incorrect for this GMAT Exam Prep question. As explained above: Calculate profit margin for each: A = $100M/$500M = 20%; B = $120M/$750M = 16%; C = $84M/$400M = 21%. Division C has the highest profit margin.
