Solution:Sher Shah Suri had a significant role in medieval India. He is considered the antecedent of Akbar as administrator imperialist.(1) Revenue reforms: Sher Shah believed that for the stability of the empire, it is essential to satisfy the peasants and make them happy. He introduced numerous reforms in land revenue administration. His land revenue collection was based on Rayatwari and was settled directly with cultivators. He adopted an improved and systematic method of measuring the land and assessing its revenue.
( 2) Administrative Reforms: Sher Shah managed his father's manor as manager and obtained the essential knowledge of administration. He had a proper knowledge of military composition, administration and financial system of Mughals. He was the head of the central government. His administration was completely centralised before victory over Bengal. He divided the whole kingdom into 47 Sirkars (districts) (According to Dr. Kanungo). He arranged a different system for Bengal province. He divided the province into 19 Sirkars (districts) (According to Satish Chandra) and appointed a military official as Shiqdar to control. A non-military official Amir-e-Bengal was also appointed for assistance. This arrangement was made for the abolishment of revolt threat.
(3) Military Reforms: Sher Shah introduced many reforms in military sector for empire consolidation. He was inspired by reforms of Alauddin Khalji. He recruited and paid the soldiers directly and every soldier had his chehra (face) recorded and his horse branded with an imperial sign, to stop fraud.
(4) Currency System Reforms: The reign of Sher Shah was an era of an experiment in the history of coins. VA Smith rightly observes "It is the basis of the existing British currency". He introduced pure gold, silver and copper coins in place of the beaten coins. His silver rupee coins weighed 178 grains and coppers Daam weighed 380 grains. Thus, credit of these reforms goes to Sher Shah Suri.
