If Jackson and Oliver work together on a project, they will complete it in 7 days. If Oliver were to work with Chloe on the same project, they will take a day longer. If Chloe and Sofia work together, they will take 100% more time than Jackson and Oliver. If Jackson and Sofia were to work together, how many more days will they take to complete the project compared to Oliver and Chloe working together?
Time taken by Jackson and Oliver in percent = 100%
Time taken by Chloe and Sofia = 100% + 100% = 200%

Time taken by Jackson and Oliver = 7 days ---- (1)
Time taken by Oliver and Chloe = 8 days ---- (2)
Time taken by Chloe and Sofia = 200% x 7 = 14 days ---- (3)

(1) + (2) + (3)
Jackson + Oliver + Oliver + Chloe + Chloe + Sofia → 7 + 8 + 14 = 29 days
Jackson + 2 (Oliver + Chloe) + Sofia → 29 days
Jackson + Sofia + 2 x 8 → 29 days
Jackson + Sofia → 29 - 16 = 13 days

More days to complete the project for Jackson and Sofia compared to Oliver and Chloe
= 13 - 8
= 5

Answer(s): 5
