If Matthew and Kaylee work together on a project, they will complete it in 6 days. If Kaylee were to work with Raeann on the same project, they will take a day longer. If Raeann and Mason work together, they will take 200% more time than Matthew and Kaylee. If Matthew and Mason were to work together, how many more days will they take to complete the project compared to Kaylee and Raeann working together?
Time taken by Matthew and Kaylee in percent = 100%
Time taken by Raeann and Mason = 100% + 200% = 300%

Time taken by Matthew and Kaylee = 6 days ---- (1)
Time taken by Kaylee and Raeann = 7 days ---- (2)
Time taken by Raeann and Mason = 300% x 6 = 18 days ---- (3)

(1) + (2) + (3)
Matthew + Kaylee + Kaylee + Raeann + Raeann + Mason → 6 + 7 + 18 = 31 days
Matthew + 2 (Kaylee + Raeann) + Mason → 31 days
Matthew + Mason + 2 x 7 → 31 days
Matthew + Mason → 31 - 14 = 17 days

More days to complete the project for Matthew and Mason compared to Kaylee and Raeann
= 17 - 7
= 10

Answer(s): 10
