Can Math and Stats Really Predict Monthly Turnover from Labor Productivity?

Give reasons for the answer

1) An employer wants to deduct Rs. 1121.90 from the monthly gross wages of Rs. 5082.06 drawn by an employee. The amount payable to the employed person is 4/73 of the annual earnings of the employee, separately levied from contributions paid by an employer to the pension and provident fund, and the interest which may have accrued thereon.

2) How true is it that the cost of labor output per man-hour (labor productivity) using mathematical and statistical techniques can eventually estimate monthly turnover?

The cost of labor output per man-hour alone cannot estimate monthly turnover, as turnover depends on a variety of factors like material cost, establishment cost, finance cost, etc. Unless all the input factors are reckoned properly on the sole basis of labor productivity, the turnover cannot be estimated.
