Answer 1

Answer:

300 people rejected part A and part B.

Step-by-step explanation:

First let's review the information given by the statement of the exercise.

1000 people surveyed.

600 reject part A, 500 part B and 200 reject no one. Therefore, of those 1000, 800 reject a party, either A or B, since 1000 respondents - 200 who do not reject = 800 who reject.

Among the respondents there are a total of 600 + 500 rejections, that is to say 1100 rejections in total.

But we know that there are only 800 respondents left, therefore the people who rejected two, is the difference between total rejections and the remaining respondents. that is to say:

1100 - 800 = 300, which means that 300 people rejected part A and part B.
