If Ryan and Jamie work together on a project, they will complete it in 12 days. If Jamie were to work with Levi on the same project, they will take a day longer. If Levi and Isaiah work together, they will take 150% more time than Ryan and Jamie. If Ryan and Isaiah were to work together, how many more days will they take to complete the project compared to Jamie and Levi working together?
Time taken by Ryan and Jamie in percent = 100%
Time taken by Levi and Isaiah = 100% + 150% = 250%

Time taken by Ryan and Jamie = 12 days ---- (1)
Time taken by Jamie and Levi = 13 days ---- (2)
Time taken by Levi and Isaiah = 250% x 12 = 30 days ---- (3)

(1) + (2) + (3)
Ryan + Jamie + Jamie + Levi + Levi + Isaiah → 12 + 13 + 30 = 55 days
Ryan + 2 (Jamie + Levi) + Isaiah → 55 days
Ryan + Isaiah + 2 x 13 → 55 days
Ryan + Isaiah → 55 - 26 = 29 days

More days to complete the project for Ryan and Isaiah compared to Jamie and Levi
= 29 - 13
= 16

Answer(s): 16
