The bar graph below shows the sale of books (in thousands) from five branches of a publishing company during 2008 and 2009.
What is the ratio of the total sales of books from branches B1, B2, and B5 in 2009 to the total sales of books from branches B2, B3, B4, and B5 in 2008?
Show answer & explanation
Correct answer: A
Explanation
The correct answer is option 1 i.e. 32 : 45.
The total sale of books from branches B1, B2, and B5 in 2009 = 85 + 99 + 136 = 320
The total sale of books from branches B2, B3, B4, and B5 in 2008 = 83 + 108 + 135 + 124 = 450
Required ratio = 320 : 450 = 32 : 45
