If the yield is 81%, what is the loss factor?

To determine the loss factor from the given yield percentage, it's essential to understand the relationship between yield and loss factor. Yield represents the percentage of the total material that is usable or produced effectively, while the loss factor signifies the percentage of material that is lost or wasted during the process.

In this case, if the yield is 81%, it means that 81% of the input material results in usable output. To find the loss factor, you can subtract the yield from 100%:

Loss Factor = 100% - Yield

Loss Factor = 100% - 81%

Loss Factor = 19%

This calculation shows that a loss factor of 19% indicates that 19% of the input material does not result in satisfactory output. Therefore, the correct interpretation of a yield of 81% leads directly to a loss factor of 19%, confirming that this is the accurate choice.
