If Evelyn and Amelia work together on a project, they will complete it in 10 days. If Amelia were to work with Dylan on the same project, they will take a day longer. If Dylan and Jack work together, they will take 160% more time than Evelyn and Amelia. If Evelyn and Jack were to work together, how many more days will they take to complete the project compared to Amelia and Dylan working together?
Time taken by Evelyn and Amelia in percent = 100%
Time taken by Dylan and Jack = 100% + 160% = 260%

Time taken by Evelyn and Amelia = 10 days ---- (1)
Time taken by Amelia and Dylan = 11 days ---- (2)
Time taken by Dylan and Jack = 260% x 10 = 26 days ---- (3)

(1) + (2) + (3)
Evelyn + Amelia + Amelia + Dylan + Dylan + Jack → 10 + 11 + 26 = 47 days
Evelyn + 2 (Amelia + Dylan) + Jack → 47 days
Evelyn + Jack + 2 x 11 → 47 days
Evelyn + Jack → 47 - 22 = 25 days

More days to complete the project for Evelyn and Jack compared to Amelia and Dylan
= 25 - 11
= 14

Answer(s): 14
