edexcel or aqa
6 numbers have a mean of mean of 10:
mean = total / number of numbers
10 = total / 6
total = 60
shit 6 numbers mb
the four numbers currently add to 12+7+15+3=37
so the final two numbers add to 60-37=23
the range is 19:
if we saw 3 is the smallest number, we could then think 22 is the biggest to make this range, but then the other number is 1, so the range is no longer 19
so therefore the two last numbers have to be 2 and 21
they have a range of 19 and add to 23
Sorry for late response but it’s aqa
And I managed to find the answer in the end thank you
