Question 119
What is approximately the ratio of sales of Red, Lemon and White refrigrators, taken together, in 2010 to that of the combined total sales of Blue and Grey ones in 2009 and 2011 taken together?
Solution
Total sales of Red, Lemon and White refrigrator taken together in 2010 = (30 + 23 + 45) = 98
Total sales of Blue and Grey ones in 2009 and 2011 taken together = (25 + 2 + 48 + 34) = 109
Ratio between them = 98 : 109 $$\cong$$ 9 : 10
Hence, option A is the correct answer.
