If Victoria and Leah work together on a project, they will complete it in 8 days. If Leah were to work with Henry on the same project, they will take a day longer. If Henry and Bryan work together, they will take 100% more time than Victoria and Leah. If Victoria and Bryan were to work together, how many more days will they take to complete the project compared to Leah and Henry working together?
Time taken by Victoria and Leah in percent = 100%
Time taken by Henry and Bryan = 100% + 100% = 200%

Time taken by Victoria and Leah = 8 days ---- (1)
Time taken by Leah and Henry = 9 days ---- (2)
Time taken by Henry and Bryan = 200% x 8 = 16 days ---- (3)

(1) + (2) + (3)
Victoria + Leah + Leah + Henry + Henry + Bryan → 8 + 9 + 16 = 33 days
Victoria + 2 (Leah + Henry) + Bryan → 33 days
Victoria + Bryan + 2 x 9 → 33 days
Victoria + Bryan → 33 - 18 = 15 days

More days to complete the project for Victoria and Bryan compared to Leah and Henry
= 15 - 9
= 6

Answer(s): 6
