A company has set standards: 0,15789 ton/minute equivalent to 6,359 minutes/ton.
One day the results were:
Tons produced: 228
Minutes worked: 1020
The production manager says: “Great day!” “Our tons/minute was 228 tons / 1020 mins, resulting in 0,22359 ton/minute. That is a dazzling 41,6% better than our standard!”
The assistant looks at him and says: “Sorry, but we were not THAT good.” “We produced 228 tons which gave us – 228 tons times 6,359 minutes per ton – about 1450 minutes to do it. We did it in 1020 minutes. The difference is 430 minutes saved against a base of the allowed 1450 minutes, only 29,6% better. Sorry….”
Who is right?
