If Levi and Victoria work together on a project, they will complete it in 4 days. If Victoria were to work with Tommy on the same project, they will take a day longer. If Tommy and Julie work together, they will take 200% more time than Levi and Victoria. If Levi and Julie were to work together, how many more days will they take to complete the project compared to Victoria and Tommy working together?
Time taken by Levi and Victoria in percent = 100%
Time taken by Tommy and Julie = 100% + 200% = 300%

Time taken by Levi and Victoria = 4 days ---- (1)
Time taken by Victoria and Tommy = 5 days ---- (2)
Time taken by Tommy and Julie = 300% x 4 = 12 days ---- (3)

(1) + (2) + (3)
Levi + Victoria + Victoria + Tommy + Tommy + Julie → 4 + 5 + 12 = 21 days
Levi + 2 (Victoria + Tommy) + Julie → 21 days
Levi + Julie + 2 x 5 → 21 days
Levi + Julie → 21 - 10 = 11 days

More days to complete the project for Levi and Julie compared to Victoria and Tommy
= 11 - 5
= 6

Answer(s): 6
