During the period between 1995 and 2000, the total number of Operators who left the Company is what percent of total number of Operators who joined the Company?

Options:

  1. 21%

  2. 29%

  3. 27%

  4. 19%

    5. Answer:

    29%
    Solution:

    Total number of Operators who left the Company during 1995 - 2000

        = (104 + 120 + 100 + 112 + 144)

        = 580.

    Total number of Operators who joined the Company during 1995 - 2000

        = (880 + 256 + 240 + 208 + 192 + 248)

        = 2024.

    Therefore Required Percentage = ( 580 x 100 ) % = 28.66% ~= 29%.
    2024
