Model 6: Efficiency

04 Try it yourself Interactive

Split the output, invert the times

Give the pair’s combined time and their efficiency ratio as two whole numbers. The console splits the daily output by the ratio, sizes the job, and reports each solo time — then points out that the times came out inverted. Use the percentage table in section 03 to turn “30% more efficient” into 13 and 10.

Together 9 days, A three times B

A 12 days, B 36

For a percentage phrasing, enter the ratio directly: 30% more efficient is 13 : 10, and 25% more is 5 : 4.
