Show answer & explanation
Correct answer: C
Explanation
The correct answer is option 3 i.e 17 : 14
Explanation:
Total number of engineers recruited by companies A and B in 2015 and 2018 = 132 + 118 + 148 + 112 = 510
Total number of engineers recruited by C and D in 2014 and 2018 = 85 + 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 : 420 = 17 : 14
