"It has been estimated earlier that there were about four hundred thousand Muslims in India in A.D. 1200. If their numbers became double in sixty to seventy years, they would have been about 3.2 million in 1400. The total population of India in 1400 has been estimated at 170 million. The Muslims would have been about 1.8 per cent of the total population with 50 to 53 Hindus to one Muslim."
