This question is not good. The math is simple, sure. But the PDA (which is most of the time a branch of the RIGHT coronary artery) supplies 2/3 posterior walls of the ventricles (FA 2019 p.281) which I'm sure is a significant portion of the left ventricle. The LAD specifically does not account for the entirety of the oxygen supply to the left ventricle, but about 45-55% according to wiki. If the question asked, "How much oxygen is delivered to the left ventricle by the LAD" it would have been acceptable.
