    I got 48 people

    I used the total to work out the percentage of the total and got 100 or one and 148 for the other. 148-100= 48

    Did anyone else do this?

    Everyone in my school got 24 but to be honest, they didn't make it clear as to whether the 0.925% and 0.625% was of the entire 16,000 or out of the two 8,000 groups

    I think you needed to divide 16000 by 2 first since there were two groups. So it was 74-50=24

    Same. The question was like 16 000 people and you had to do 16 000 times 0.625/100 and 16 000 times 0.925/100

    I got 48 too to be honest, but my friends said that the 16000 people were divided into 2 groups, anyways I think they might just cut 1 mark for not dividing by 2.

    tbh i think it is 48, i don't think you need to divide by 2 bc it didn't ask for just one group, it asked for the difference between the two values which were of both groups, so i'm assuming it is the full 16000

    It asked for the difference between the two groups, and if you don't half it you're assuming both groups has 16000 people rather than 8000

    Let's hope that's what they wanted😁. I always forget the questions when I come out of the exam so I'm always slightly unsure of my own answers 😂.

      it said both groups
      8000 in both groups
      it told us how many people in both groups contracted HIV
      we work out the difference between the amount of people who contracted HIV
