What is the total of 25% + 35% + 20% + 20%?

To find the total of the percentages 25%, 35%, 20%, and 20%, you simply add them together:

25% + 35% + 20% + 20% = 100%.

This calculation reveals that the sum of these percentages equals 100%.

Percentages specifically represent portions of a whole, and when adding several percentages together that are meant to describe parts of a single complete entity, reaching a total of 100% indicates that the entirety of that entity has been accounted for. In this case, the addition of the given percentages confirms they cover the complete range.

The other choices represent totals that exceed or fall short of the complete sum of the provided percentages, which shows that while they might be plausible in different contexts, they do not represent the accurate cumulative total in this particular instance.
