If Alexander and Hazel work together on a project, they will complete it in 5 days. If Hazel were to work with Jackson on the same project, they will take a day longer. If Jackson and Gavin work together, they will take 160% more time than Alexander and Hazel. If Alexander and Gavin were to work together, how many more days will they take to complete the project compared to Hazel and Jackson working together?
Time taken by Alexander and Hazel in percent = 100%
Time taken by Jackson and Gavin = 100% + 160% = 260%

Time taken by Alexander and Hazel = 5 days ---- (1)
Time taken by Hazel and Jackson = 6 days ---- (2)
Time taken by Jackson and Gavin = 260% x 5 = 13 days ---- (3)

(1) + (2) + (3)
Alexander + Hazel + Hazel + Jackson + Jackson + Gavin → 5 + 6 + 13 = 24 days
Alexander + 2 (Hazel + Jackson) + Gavin → 24 days
Alexander + Gavin + 2 x 6 → 24 days
Alexander + Gavin → 24 - 12 = 12 days

More days to complete the project for Alexander and Gavin compared to Hazel and Jackson
= 12 - 6
= 6

Answer(s): 6
