It is question 26 (ii).

http://www.boardofstudies.nsw.edu.au/hsc_exams/hsc2008exams/pdf_doc/2008HSC-general-mathematics.pdf


The answer from the marking centre is apparently 58%. But I don't understand how the total can be counted to the people aged under 40 and people aged over 40. That is the total amount of the people who liked the movie, how can the total be counted to that? Isn't the answer supposed to be 29%

because 102 times 100 divided by 305 = 29%

Please help with this. I can't understand how the total amount of people who disliked the movie can be counted to 102?

answer's 24%

Should be 24% in theory, You fill in the boxes. Missing total is 73. 73-31 = 42.



=24%
