If Audrey and Aubrey work together on a project, they will complete it in 10 days. If Aubrey were to work with Maya on the same project, they will take a day longer. If Maya and Ava work together, they will take 130% more time than Audrey and Aubrey. If Audrey and Ava were to work together, how many more days will they take to complete the project compared to Aubrey and Maya working together?
Time taken by Audrey and Aubrey in percent = 100%
Time taken by Maya and Ava = 100% + 130% = 230%

Time taken by Audrey and Aubrey = 10 days ---- (1)
Time taken by Aubrey and Maya = 11 days ---- (2)
Time taken by Maya and Ava = 230% x 10 = 23 days ---- (3)

(1) + (2) + (3)
Audrey + Aubrey + Aubrey + Maya + Maya + Ava → 10 + 11 + 23 = 44 days
Audrey + 2 (Aubrey + Maya) + Ava → 44 days
Audrey + Ava + 2 x 11 → 44 days
Audrey + Ava → 44 - 22 = 22 days

More days to complete the project for Audrey and Ava compared to Aubrey and Maya
= 22 - 11
= 11

Answer(s): 11
