Passage: As a trading body, the first remit of the company was to maximise its profits and with taxation rights, the profits to be obtained from Bengal came from land tax as well as trade tariffs. It has been suggested that the Company increased tax rates from 10 percent to up to 50 percent of the value of the agricultural produce, citing the pioneering work of R.C. Dutt, but in reality he makes no such claim. In the first years of the rule of the British East India Company, the total land tax income was doubled and most of this revenue flowed out of the country. As the famine approached its height in April 1770, the Company announced that the land tax for the following year was to be increased by a further 10 percent.

Question: The company sought to obtain profits from which two means?
land tax as well as trade tariffs
