The given Bar Graph presents the sales of the number of books (in thousands) by six branches of a publishing company during two consecutive years 2000 and 2001.
Question 56
The ratio of total sales by all branches for the year 2001 to total sales by all branches for the year 2000 is:
Solution
As Given in above Bar Graph
Total sales in 2001 = sum of sales of all companies in 2001
$$\Rightarrow$$ Total sales in 2001 = 105 + 65 + 110 + 95 +95 + 80
$$\Rightarrow$$ Total sales in 2001 = 550
Total sales in 2000 = sum of sales of all companies in 2000
$$\Rightarrow$$ Total sales in 2000 = 80 + 75 + 95 + 85 + 75 + 70
$$\Rightarrow$$ Total sales in 2000 = 480
Required Ratio $$\Rightarrow 550 : 480 \Rightarrow 55:48$$
