Question 63

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 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?

Solution

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 = $$\frac{520 - 500}{500} \times 100 = \frac{20}{500} \times$$ 100 = 4%
