If Salik and Nora work together on a project, they will complete it in 5 days. If Nora were to work with Aaron on the same project, they will take a day longer. If Aaron and Josiah work together, they will take 60% more time than Salik and Nora. If Salik and Josiah were to work together, how many more days will they take to complete the project compared to Nora and Aaron working together?
Time taken by Salik and Nora in percent = 100%
Time taken by Aaron and Josiah = 100% + 60% = 160%

Time taken by Salik and Nora = 5 days ---- (1)
Time taken by Nora and Aaron = 6 days ---- (2)
Time taken by Aaron and Josiah = 160% x 5 = 8 days ---- (3)

(1) + (2) + (3)
Salik + Nora + Nora + Aaron + Aaron + Josiah → 5 + 6 + 8 = 19 days
Salik + 2 (Nora + Aaron) + Josiah → 19 days
Salik + Josiah + 2 x 6 → 19 days
Salik + Josiah → 19 - 12 = 7 days

More days to complete the project for Salik and Josiah compared to Nora and Aaron
= 7 - 6
= 1
