Question

For which of the following categories, the percentage increase in the number of employees working in the company from 2006 to 2011 was the maximum?

• A. Managers
• B. Technicians
• C. Operators
• D. Accountants

Answer 1

The correct option is A Managers

Number of managers working in the company in 2006 = 760
In 2011 = (760 + 280 + 179 + 148 + 160 + 193) - (120 + 92 + 88 + 72 + 96) = 1252
Percentage increase in the number of managers = $(=\frac{1252-760}{760})\times 100=64.73\%$
$\Rightarrow$ Number of technicians working in the company in 2006 = 1200
In 2011 = (1200 + 272 + 240 + 236 + 256 + 288) - (120 + 128 + 96 + 100 + 112) = 1936
Percentage increase in the number of technicians
$=\left(\frac{1936-1200}{1200}\right)\times 100=61.33\%$
Number of operators working in the company in 2006 = 880
In 2011 = (880 + 256 + 240 + 208 + 192 + 248) - (104 + 120 + 100 + 112 + 144) = 1444
Percentage increase in the number of operators
$=\left(\frac{1444-880}{880}\right)\times 100=64.09\%$
Number of accountants working in the company in 2006 = 1160
In 2011 = (1160 + 200 + 224 + 248 + 272 + 260) - (100 + 104 + 96 + 88 + 92) = 1884
Percentage increase in the number of accountants
$=\frac{(1884-1160)}{1160}\times 100=62.41\%$
Clearly, the percentage increase is maximum in case of managers.
