The bar graph given below shows the number of workers (in thousands) in company P and company Q for the given years What is the ratio of total number of workers of company P in year 2011 and 2012 to the total number of workers of company Q in the year 2012 and 2013? Correct Answer 8 : 7

Calculation:

Total number of workers of company P in year 2011 and 2012 = 60 + 20 = 80

Total number of workers of company Q in year 2012 and 2013 = 30 + 40 = 70

∴ Required ratio = 80 : 70 = 8 : 7
