If Avery and Zoey work together on a project, they will complete it in 10 days. If Zoey were to work with Gabriel on the same project, they will take a day longer. If Gabriel and Jackson work together, they will take 120% more time than Avery and Zoey. If Avery and Jackson were to work together, how many more days will they take to complete the project compared to Zoey and Gabriel working together?
Time taken by Avery and Zoey in percent = 100%
Time taken by Gabriel and Jackson = 100% + 120% = 220%

Time taken by Avery and Zoey = 10 days ---- (1)
Time taken by Zoey and Gabriel = 11 days ---- (2)
Time taken by Gabriel and Jackson = 220% x 10 = 22 days ---- (3)

(1) + (2) + (3)
Avery + Zoey + Zoey + Gabriel + Gabriel + Jackson → 10 + 11 + 22 = 43 days
Avery + 2 (Zoey + Gabriel) + Jackson → 43 days
Avery + Jackson + 2 x 11 → 43 days
Avery + Jackson → 43 - 22 = 21 days

More days to complete the project for Avery and Jackson compared to Zoey and Gabriel
= 21 - 11
= 10

Answer(s): 10
