Question

I have no clue how to answer this or where to start

Answer 1

It’s quite simple. Take the total percentage of people from this- 25*2 and add 43. It’s 93%

Answer 2

You can add up the percentages. When doing this, I am also thinking that there are 100 residents in all.
From 600 to 649, there are 25 people or 25%.
From 650 to 699, there are ABOUT 45 people or 45% (43 people)
From 700 to 749, there are 25 people or 25%.
Let's add it up.
25+25+43
93
Letter A, 93%.
