If Violet and Tommy work together on a project, they will complete it in 12 days. If Tommy were to work with Kaylee on the same project, they will take a day longer. If Kaylee and Hannah work together, they will take 50% more time than Violet and Tommy. If Violet and Hannah were to work together, how many more days will they take to complete the project compared to Tommy and Kaylee working together?
Time taken by Violet and Tommy in percent = 100%
Time taken by Kaylee and Hannah = 100% + 50% = 150%

Time taken by Violet and Tommy = 12 days ---- (1)
Time taken by Tommy and Kaylee = 13 days ---- (2)
Time taken by Kaylee and Hannah = 150% x 12 = 18 days ---- (3)

(1) + (2) + (3)
Violet + Tommy + Tommy + Kaylee + Kaylee + Hannah → 12 + 13 + 18 = 43 days
Violet + 2 (Tommy + Kaylee) + Hannah → 43 days
Violet + Hannah + 2 x 13 → 43 days
Violet + Hannah → 43 - 26 = 17 days

More days to complete the project for Violet and Hannah compared to Tommy and Kaylee
= 17 - 13
= 4

Answer(s): 4
