If Lilian and Zoey work together on a project, they will complete it in 11 days. If Zoey were to work with Chloe on the same project, they will take a day longer. If Chloe and Gabriel work together, they will take 200% more time than Lilian and Zoey. If Lilian and Gabriel were to work together, how many more days will they take to complete the project compared to Zoey and Chloe working together?
Time taken by Lilian and Zoey in percent = 100%
Time taken by Chloe and Gabriel = 100% + 200% = 300%

Time taken by Lilian and Zoey = 11 days ---- (1)
Time taken by Zoey and Chloe = 12 days ---- (2)
Time taken by Chloe and Gabriel = 300% x 11 = 33 days ---- (3)

(1) + (2) + (3)
Lilian + Zoey + Zoey + Chloe + Chloe + Gabriel → 11 + 12 + 33 = 56 days
Lilian + 2 (Zoey + Chloe) + Gabriel → 56 days
Lilian + Gabriel + 2 x 12 → 56 days
Lilian + Gabriel → 56 - 24 = 32 days

More days to complete the project for Lilian and Gabriel compared to Zoey and Chloe
= 32 - 12
= 20

Answer(s): 20
