Explanation:

Alauddin implemented price control measures for a wide variety of market goods.Alauddin's courtier Amir Khusrau and the 14th century writer Hamid Qalandar suggest that Alauddin introduced these changes for public welfare.However, Barani states that Alauddin wanted to reduce the prices so that low salaries were acceptable to his soldiers, and thus, to maintain a large army. In addition, Barani suggests that the Hindu traders indulged in profiteering, and Alauddin's market reforms resulted from the Sultan's desire to punish the Hindus. To ensure that the goods were sold at regulated prices, Alauddin appointed market supervisors and spies, and received independent reports from them. To prevent a black market, his administration prohibited peasants and traders from storing the grains, and established government-run granaries, where government's share of the grain was stored. The government also forced the transport workers to re-settle in villages at specific distances along the Yamuna river to enable rapid transport of grain to Delhi.
