Question 124, Data Sufficiency Sample Questions in GMAT 12th Edition Official Review. The answer given is A.
I think this is wrong, please correct me.
The explanation by book for answer A begins with : "given that 40 voters did not respond 'Favorable' for either candidate, and there were 100 voters surveyed. So the number of candidates who responded 'Favorable' to at least one candidate is 100 - 40."
I think this premise is wrong, since the voters had choice to pick 'Not Sure', how can you be sure 60 is the number of people voting 'Favorable' for at least one candidate?
I am probably wrong - please correct the flaw in my thinking. (Did not post entire question, cause it may be copyrighted).
40 did not respond favorable..that means they voted the other options (unfavorable and not sure)
it's assuming you have to vote one of three ways..so not favorable means you voted unfavorable or not sure
is this the problem?
