After the battles that they fought, they were able to collect the booty from the land and add it to their treasury, but this was not the only way of gaining money from the land.
They gained gifts from their subjects so that they would be noticeable
to their emperors.
But 2/3rds of the money in the treasury was from the taxation
that was put upon the people. The land was divided into crown
lands and Jagirs.
Peasants paid 1/3 of their harvest to the treasury. Some rulers were tolerant to the bad weather that the farmers were put up against and reduced or even suspended taxes, but most were not as kind and would punish the peasants for not paying their dues.
Crown Lands taxes were collected by the emperor's
agents and paid straight to the treasury.
Jagirs were pieces of land, which were transferred to the
temporary mansabdars, or officers who ran them. And the taxes
from this land went to the salaries of the temp. mansabdars and
the treasury.
India also had a trade industry, which traded things manly by
the west coasts rivers and seas to go the Europe.

The Imports were
gold, silver, bullion bars (which were used to make coins), horses,
ivory, precious stones, and wine.
