Solution:The attempt by Alauddin Khalji to control the market prices was highly successful.Alauddin Khalji's measures to control the market prices were one of the most important policy initiatives of his reign. since Alauddin wanted to maintain a vast standing army, he therefore, lowered the prices of the commodities of daily use. He established separate markets in Delhi,
(a) Grain Market (Mandi) for grain
(b) Clothes and Groceries market for clothes, sugar, dry fruits, butter and oil
(c) Market for horse, slaves, cattle etc.
(d) Market for miscellaneous commodities.
To ensure implementation, each market was under he control of a superintendent called Shahna-i-Mandi who was assisted by an intelligence officer. Apart from Shahna-i-Mandi Alaudin received daily reports of the market from two other independent sources, barids (intelligence officer) and munhiyans (Secret spies).
