OA is B.
Here is my issue with this question:
From stmt 1) we can find out what percentage has paid 81% or more. The question has asked us to find out the fraction for 80% or less.
Since we know the percentage for 81% or more, if we subtract from 100% we would get 80% or less right? Once we get the percentage, then we can find out the fraction.
Something tells me that I am missing something in the above, but I couldn't spot it. Could someone throw your thoughts?
subtracting from 100 will, in this case, give: %ge of people who paid LESS THAN 81%
it can be 85.5 %
