If Aubrey and Dylan work together on a project, they will complete it in 10 days. If Dylan were to work with Bryan on the same project, they will take a day longer. If Bryan and Kaylee work together, they will take 120% more time than Aubrey and Dylan. If Aubrey and Kaylee were to work together, how many more days will they take to complete the project compared to Dylan and Bryan working together?
Time taken by Aubrey and Dylan in percent = 100%
Time taken by Bryan and Kaylee = 100% + 120% = 220%

Time taken by Aubrey and Dylan = 10 days ---- (1)
Time taken by Dylan and Bryan = 11 days ---- (2)
Time taken by Bryan and Kaylee = 220% x 10 = 22 days ---- (3)

(1) + (2) + (3)
Aubrey + Dylan + Dylan + Bryan + Bryan + Kaylee → 10 + 11 + 22 = 43 days
Aubrey + 2 (Dylan + Bryan) + Kaylee → 43 days
Aubrey + Kaylee + 2 x 11 → 43 days
Aubrey + Kaylee → 43 - 22 = 21 days

More days to complete the project for Aubrey and Kaylee compared to Dylan and Bryan
= 21 - 11
= 10

Answer(s): 10
