If Jamie and Violet work together on a project, they will complete it in 12 days. If Violet were to work with Robert on the same project, they will take a day longer. If Robert and Michael work together, they will take 100% more time than Jamie and Violet. If Jamie and Michael were to work together, how many more days will they take to complete the project compared to Violet and Robert working together?
Time taken by Jamie and Violet in percent = 100%
Time taken by Robert and Michael = 100% + 100% = 200%

Time taken by Jamie and Violet = 12 days ---- (1)
Time taken by Violet and Robert = 13 days ---- (2)
Time taken by Robert and Michael = 200% x 12 = 24 days ---- (3)

(1) + (2) + (3)
Jamie + Violet + Violet + Robert + Robert + Michael → 12 + 13 + 24 = 49 days
Jamie + 2 (Violet + Robert) + Michael → 49 days
Jamie + Michael + 2 x 13 → 49 days
Jamie + Michael → 49 - 26 = 23 days

More days to complete the project for Jamie and Michael compared to Violet and Robert
= 23 - 13
= 10

Answer(s): 10
