If Scarlett and Isabella work together on a project, they will complete it in 5 days. If Isabella were to work with Michael on the same project, they will take a day longer. If Michael and Chloe work together, they will take 140% more time than Scarlett and Isabella. If Scarlett and Chloe were to work together, how many more days will they take to complete the project compared to Isabella and Michael working together?
Time taken by Scarlett and Isabella in percent = 100%
Time taken by Michael and Chloe = 100% + 140% = 240%

Time taken by Scarlett and Isabella = 5 days ---- (1)
Time taken by Isabella and Michael = 6 days ---- (2)
Time taken by Michael and Chloe = 240% x 5 = 12 days ---- (3)

(1) + (2) + (3)
Scarlett + Isabella + Isabella + Michael + Michael + Chloe → 5 + 6 + 12 = 23 days
Scarlett + 2 (Isabella + Michael) + Chloe → 23 days
Scarlett + Chloe + 2 x 6 → 23 days
Scarlett + Chloe → 23 - 12 = 11 days

More days to complete the project for Scarlett and Chloe compared to Isabella and Michael
= 11 - 6
= 5

Answer(s): 5
