The following bar graph shows the sales of books (in thousands) from six branches of a publishing company during two consecutive years 2018 and 2019 .
What is the ratio of the total sales of the second branch for both years to the total sales of the fourth branch for both years?
Answer & explanation

Ratio of the total sales of the second branch for both years to the total sales of the fourth branch for both years,

= 140 : 180
= 7 : 9
