If Josiah and Natalie work together on a project, they will complete it in 5 days. If Natalie were to work with Dylan on the same project, they will take a day longer. If Dylan and Jacob work together, they will take 100% more time than Josiah and Natalie. If Josiah and Jacob were to work together, how many more days will they take to complete the project compared to Natalie and Dylan working together?
Time taken by Josiah and Natalie in percent = 100%
Time taken by Dylan and Jacob = 100% + 100% = 200%

Time taken by Josiah and Natalie = 5 days ---- (1)
Time taken by Natalie and Dylan = 6 days ---- (2)
Time taken by Dylan and Jacob = 200% x 5 = 10 days ---- (3)

(1) + (2) + (3)
Josiah + Natalie + Natalie + Dylan + Dylan + Jacob → 5 + 6 + 10 = 21 days
Josiah + 2 (Natalie + Dylan) + Jacob → 21 days
Josiah + Jacob + 2 x 6 → 21 days
Josiah + Jacob → 21 - 12 = 9 days

More days to complete the project for Josiah and Jacob compared to Natalie and Dylan
= 9 - 6
= 3
