If Audrey and Tommy work together on a project, they will complete it in 10 days. If Tommy were to work with Zoey on the same project, they will take a day longer. If Zoey and Lucas work together, they will take 120% more time than Audrey and Tommy. If Audrey and Lucas were to work together, how many more days will they take to complete the project compared to Tommy and Zoey working together?
Time taken by Audrey and Tommy in percent = 100%
Time taken by Zoey and Lucas = 100% + 120% = 220%

Time taken by Audrey and Tommy = 10 days ---- (1)
Time taken by Tommy and Zoey = 11 days ---- (2)
Time taken by Zoey and Lucas = 220% x 10 = 22 days ---- (3)

(1) + (2) + (3)
Audrey + Tommy + Tommy + Zoey + Zoey + Lucas → 10 + 11 + 22 = 43 days
Audrey + 2 (Tommy + Zoey) + Lucas → 43 days
Audrey + Lucas + 2 x 11 → 43 days
Audrey + Lucas → 43 - 22 = 21 days

More days to complete the project for Audrey and Lucas compared to Tommy and Zoey
= 21 - 11
= 10

Answer(s): 10
