The total number of engineers recruited by company A in 2014 to 2017 is what percentage more than the total number of engineers recruited by all four companies in 2019?
Answer & explanation
Correct answer: option 4
Total number of engineers recruited in 2019 = 150 + 118 + 110 + 122 = 500
Total number of engineers recruited by A in 2014 to 2017 = 120 + 132 + 128 + 140
= 520
Required percentage = \(\frac{520 - 500}{500}\) × 100
= \(\frac{20}{500}\) × 100
= 4%
