Question 10. Why did the rulers collect regular taxes? (a) For building huge forts (b) For maintaining big armies (c) Both (a) and (b) (d) None of these Answer
As the rulers of the mahajanapadas were (a) building huge forts (b) maintaining big armies, they needed more resources. And they needed officials to collect these. So, instead of depending on occasional gifts brought by people, as in the case of the raja of the janapadas, they started collecting regular taxes.
