There are 100 men in town. Out of which 85% were married, 70% have a phone, 75% own a car, 80% own a house. What is the maximum number of people who are married, own a phone, own a car and own a house?  Choose the correct choice
A) 20 B) 15 C) 10 D) 5 E) None of these
% of married = 85%   % of phone = 70%   % of car = 75%   % of house = 80.   Therefore,   % of not married = 15%   % of not having phone = 30%   % of not owning car = 25%   % of not having house = 20%   So, % of not having any of these things = 15 +25+ 30 + 20=
