A survay of the movie goers showed that 20% saw all
three movies of the month, 10% have not seen any of the
top movies of the month, and each of the movie
has been seen by 47%, 48% and 55% of the survayed
audience respectively. What percent of the survayed
saw only two of the top three movies of the month?

I got 40% somehow.
90 = 47 + 48 + 55 -20 - (total who saw only 2 movies)
answer = 40%

Formula
Part 1 + Part 2 + Part 3 - More than 1+ NONE = Total
48 + 47 + 55 -20 + 10 = 140% thus, 40% is still double counted.
Thus 40 percent saw only 2 movies.
