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.
| Company | A | B | C | D |
| Year | ||||
| 2014 | 120 | 90 | 85 | 105 |
| 2015 | 132 | 118 | 93 | 97 |
| 2016 | 128 | 98 | 94 | 100 |
| 2017 | 140 | 106 | 98 | 116 |
| 2018 | 148 | 112 | 105 | 125 |
| 2019 | 150 | 118 | 110 | 122 |
The number of the years in which the number of engineers recruited by company D is less than the average number of engineers recruited by B in the given six years, is:
Show answer & explanation
Correct answer: A
Explanation
The correct answer is option 1 i.e 3
Explanation:
Sum of the number of engineers recruited by B in the given six years = 90 + 119 + 98 + 106 + 112 + 118 = 643
Average number of engineers recruited by B in the given six years = 643/6 = 107.16
∴ 3 years (2014, 2015, 2016) in which the number of engineers recruited by company D is less than the average number of engineers recruited by B in the given six years
