The given table represents the number of engineers recruited by four companies A, B, C and D over the years. Study the table carefully and answer the question that follows.
The ratio of the total number of engineers recruited by companies A and B in 2015 and 2018 to the total number of engineers recruited by C and D in 2014 and 2018,is:
Total number of engineers recruited by companies A and B in 2015 and 2018Â = 132 +Â 118 + 148 + 112Â = 510
Total number of engineers recruited by C and D in 2014 and 2018 = 85 +Â 105 + 105 + 125 = 420
The ratio of the total number of engineers recruited by companies A and B in 2015 and 2018 to the total number of engineers recruited by C and D in 2014 and 2018 = 510 :Â 420 = 17 : 14
