Multiple Choice

If IRC is 40% and ITC is 60%, their sum is 100%.

Explanation:
When two percentages describe parts of the same whole, they add up to 100 percent. If IRC is 40 percent and ITC is 60 percent, together they cover the entire whole with no overlap and no missing portion, so their sum is 100 percent. The total 100 percent is the only one that fits this scenario, while the other totals would require a missing piece or double counting that isn’t present here.
