The fact that your visa was approved for both Tourist and Business categories does not mean that you can enter once for each of those categories - it means that for any entries you are able to partake in tourist and/or business activities.
The number of times you can use your visa will depend on the details of the visa that was issued.
Most Indian e-visas's are "Double" entry, which means that you are allowed enter the country twice using the same visa. If you check your approval there should be a heading "Entry type" that is either "Single" (only one entry allowed), "Double" (up to 2 entries allowed) or "Multiple" (any number of entries allowed").
Presuming your visa is either "Double" or "Multiple" then you're good to re-enter a second time within the expiry of your visa.
