What is the best approach to solve this advanced overlapping set problem?
124:
Candidate M (40) Favorable (20) Unfavorable (40) Not Sure
Candidate N (30) Favorable (35) Unfavorable (35) Not Sure
The table above shows the results of a survey of
100 voters who each responded "Favorable" or
"Unfavorable" or "Not Sure" when asked about their
impressions of Candidate M and of Candidate N. What
was the number of voters who responded "Favorable"
for both candidates?
(1) The number of voters who did not respond
"Favorable" for either candidate was 40.
(2) The number of voters who responded
"Unfavorable" for both candidates was 10.
