A company conducted a survey about its two brands, A and B. x percent of respondents liked product A, (x – 20) percent liked product B, 23 percent liked both products, and 23 percent liked neither product. What is the minimum number D of people surveyed by the company?	Choose the correct option
A) 46	B) 80	C) D.90	D) D.100	E) 200
100 = x + x - 20 + 23 - 23   x = 60,   So, Product A = 60%, Product B = 40%, Both = 23%, Neither = 23%   23% of the total no. of people should be an integer. So, A,BC are out.   60% of D and 40% of D are both integers. So, D satisfies all conditions.   So, answer is D.100.
