If Claire and Raeann work together on a project, they will complete it in 9 days. If Raeann were to work with Emily on the same project, they will take a day longer. If Emily and Henry work together, they will take 200% more time than Claire and Raeann. If Claire and Henry were to work together, how many more days will they take to complete the project compared to Raeann and Emily working together?
Time taken by Claire and Raeann in percent = 100%
Time taken by Emily and Henry = 100% + 200% = 300%

Time taken by Claire and Raeann = 9 days ---- (1)
Time taken by Raeann and Emily = 10 days ---- (2)
Time taken by Emily and Henry = 300% x 9 = 27 days ---- (3)

(1) + (2) + (3)
Claire + Raeann + Raeann + Emily + Emily + Henry → 9 + 10 + 27 = 46 days
Claire + 2 (Raeann + Emily) + Henry → 46 days
Claire + Henry + 2 x 10 → 46 days
Claire + Henry → 46 - 20 = 26 days

More days to complete the project for Claire and Henry compared to Raeann and Emily
= 26 - 10
= 16

Answer(s): 16
