If Joshua and Ryan work together on a project, they will complete it in 12 days. If Ryan were to work with Aubrey on the same project, they will take a day longer. If Aubrey and Rael work together, they will take 200% more time than Joshua and Ryan. If Joshua and Rael were to work together, how many more days will they take to complete the project compared to Ryan and Aubrey working together?
Time taken by Joshua and Ryan in percent = 100%
Time taken by Aubrey and Rael = 100% + 200% = 300%

Time taken by Joshua and Ryan = 12 days ---- (1)
Time taken by Ryan and Aubrey = 13 days ---- (2)
Time taken by Aubrey and Rael = 300% x 12 = 36 days ---- (3)

(1) + (2) + (3)
Joshua + Ryan + Ryan + Aubrey + Aubrey + Rael → 12 + 13 + 36 = 61 days
Joshua + 2 (Ryan + Aubrey) + Rael → 61 days
Joshua + Rael + 2 x 13 → 61 days
Joshua + Rael → 61 - 26 = 35 days

More days to complete the project for Joshua and Rael compared to Ryan and Aubrey
= 35 - 13
= 22

Answer(s): 22
