Too much for poor math.
Look.
Pakistan: 100 million Muslims
India: 120 million Muslims
Total S.Asia: 220 million Muslims
Therefore % of S.Asian Muslims in India: (120/220)*100=54.5%(Majority of S.Asian Muslims in India)

I misunderstood. I thought the person was claiming that India has a larger percentage of Moslems than Pakistan. As percent of total population, Pakistan has more Moslems (by definition). If you control for area, I think Pakistan will still have more Moslems.
