Hi everyone, I apologize in advance for my poor writing in English.

My problem is the following: I work in a textile factory, and we have standard (how many pieces a day we have to make to the efficiency was 100%).

The person responsible for calculating the standard and our efficiency does not want to give us the formula, so we must try to figure it out for ourselves.

For example:

We need 377 pieces for 100% fulfillment.

But we made 400 pieces.

The person who calculates efficiency got a score of 126.41%.

Can anyone understand how she was able to get this result?

The formula should be as follows:

400 is the number of pieces we made.

81 is the number of pieces we need to make.

510 is the number of minutes per day (8.5h)

30 is a breakfast break

15 is a cigar break.

100% is maximum efficiency.

So of the 510 minutes spent at work, we lose 45 minutes on breaks.

(400 * 81) / {510 - (30 +15)} * 100% = result
