If Aaron and Josiah work together on a project, they will complete it in 8 days. If Josiah were to work with Caleb on the same project, they will take a day longer. If Caleb and Bryan work together, they will take 50% more time than Aaron and Josiah. If Aaron and Bryan were to work together, how many more days will they take to complete the project compared to Josiah and Caleb working together?
Time taken by Aaron and Josiah in percent = 100%
Time taken by Caleb and Bryan = 100% + 50% = 150%

Time taken by Aaron and Josiah = 8 days ---- (1)
Time taken by Josiah and Caleb = 9 days ---- (2)
Time taken by Caleb and Bryan = 150% x 8 = 12 days ---- (3)

(1) + (2) + (3)
Aaron + Josiah + Josiah + Caleb + Caleb + Bryan → 8 + 9 + 12 = 29 days
Aaron + 2 (Josiah + Caleb) + Bryan → 29 days
Aaron + Bryan + 2 x 9 → 29 days
Aaron + Bryan → 29 - 18 = 11 days

More days to complete the project for Aaron and Bryan compared to Josiah and Caleb
= 11 - 9
= 2

Answer(s): 2
