Regarding the quote about the British East India Company, it's worth noting that employees of the company had notoriously poor pay and were half-expected to set up their own personal ventures while in India to support themselves. The company was also poorly administered, and there was almost certainly a great deal of embezzlement going on (in response to the poor pay). So while the expected mathematics was probably comparatively simple, the numbers probably didn't add up (which is the kind of thing we'd expect a Commons committee to inquire into).
