Hi mimishyu,
Since this discussion is spread over several posts in this thread, I'm going to consolidate all of the relevant information here:
Based on the table (and the description above it), we can deduce that some people in this survey responded to MORE than one category. Here's why:
1) If you add up all of the percentages in the first column, you end up with a total of 110%. That would not happen if each person chose just one reason. Thus, some of those people chose 2 (or more) reasons.
2) The text above the survey states that the survey "...was designed to help determine what respondents see as the potential BENEFITS of adding a website". The word "benefits" is plural; if each person chose just ONE option, then the wording would have stated "...was designed to help determine what respondents see as the potential BENEFIT (singular) of adding a website".
Thus, while we don't know which people chose more than one option from the list, we do know that some of them did.
Question 2 from the set of 3 focuses on a COMPARISON: is one number (PMS) less than 25% of another number (ECB). Your calculations here are correct; we have....
Preserve Market Share(PMS) : 28 Respondents
Expand Customer Base (ECB): 30 Respondents
In simple terms, is 28 less than 30? YES - it clearly is. This does not change regardless of the number of people who are in "both" groups because the overall totals (28 and 30) will still be the same. You are given EXACT data/numbers to work with here, and no 'hypothetical' situation changes those numbers.
Even if you did not do that math though, you can still determine that Question 2 can be inferred based on the percents in each column of the table:
-In the Latino column...what is 25% of 26%? It's 6.5%...Is PMS less than ECB?... is 6% less than 6.5%?.....YES
-In the African American column...what is 25% of 29%? It's 7.25%...Is PMS less than ECB?.....is 6% less than 7.25%....YES
-In the Asian American column...what is 25% of 25%? It's 6.25%....Is PMS less than ECB?.....is 4% less than 6.25%....YES
-In the Native American column...what is 25% of 25%? It's 6.25%....Is PMS less than ECB?....is 6% less than 6.25%....YES
Since each individual column gives us a 'YES' result, summing up all of those numbers would also give us a "YES" result (we'd just be dealing with one big calculation instead of four smaller ones.

In integrated reasoning, for something to be "inferred," it must be true. For example, if you can find a true or false answer for a question, if the answer is false, it is not inferrable. IR inference and DS differ in this way.
