Show answer & explanation
Correct answer: D
Explanation
The correct answer is option 4 i.e 4
Explanation:
The total number of engineers recruited by company A in 2014 to 2017 = 120 + 132 + 128 + 140 = 520
The total number of engineers recruited by all four companies in 2019 = 150 + 118 + 110 + 122 = 500
Required percentage = (520 - 500) / (500) × 100 = 20/500 × 100 = 4%
