Step-by-step explanation:
The Mughal Empire in India was founded in 1526. To estimate the approximate population of the Ottoman Empire when the Mughal Empire was founded, we can look at the population numbers given for different years. The population of the Ottoman Empire was 11,692,480 in 1500 and 15,000,000 in 1520. Since the Mughal Empire was founded in 1526, we can assume that the population of the Ottoman Empire in 1520 would be somewhere between these two numbers.
Therefore, the approximate population of the Ottoman Empire when the Mughal Empire was founded in 1520 was around 15 million.
