Question

The graph below shows the number of notepads that each location of a business used last year. The number of departments per location are presented in the table below. Four of the locations used the same number of notepads per department, but the Northwest and Central offices used fewer notepads per department. The graph shows that the Northwest location used the same number of notepads as the Southeast location overall. If the Northwest location used fewer notepads per department, which of the following could be the number of departments for the Northwest location?

Answer 1

So we plot the values over the bars

Now we identify that each line is separated by 2

Answer: Then we get central as 8 and northwest as 6
