If Julian and Leah work together on a project, they will complete it in 5 days. If Leah were to work with Abigail on the same project, they will take a day longer. If Abigail and Gabriel work together, they will take 200% more time than Julian and Leah. If Julian and Gabriel were to work together, how many more days will they take to complete the project compared to Leah and Abigail working together?
Time taken by Julian and Leah in percent = 100%
Time taken by Abigail and Gabriel = 100% + 200% = 300%

Time taken by Julian and Leah = 5 days ---- (1)
Time taken by Leah and Abigail = 6 days ---- (2)
Time taken by Abigail and Gabriel = 300% x 5 = 15 days ---- (3)

(1) + (2) + (3)
Julian + Leah + Leah + Abigail + Abigail + Gabriel → 5 + 6 + 15 = 26 days
Julian + 2 (Leah + Abigail) + Gabriel → 26 days
Julian + Gabriel + 2 x 6 → 26 days
Julian + Gabriel → 26 - 12 = 14 days

More days to complete the project for Julian and Gabriel compared to Leah and Abigail
= 14 - 6
= 8

Answer(s): 8
