Explanation:

Alauddin Khalji maintained a large permanent standing army and paid them in cash from the royal treasury. The introduction of paying salaries in cash to the soldiers led to price regulations popularly called as Market Reforms. Alauddin Khalji established four separate markets in Delhi, one for grain; another for cloth, sugar, dried fruits, butter and oil; a third for horses, slaves and cattle; and a fourth for miscellaneous commodities.
Apart from market reforms, Alauddin Khalji took important steps in the land revenue administration. He was the first Sultan of Delhi who ordered for the measurement of land. Even the big landlords could not escape from paying land tax. Land revenue was collected in cash in order to enable the Sultan to pay the soldiers in cash. His land revenue reforms provided a basis for the future reforms of Sher Shah and Akbar.
