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

Time taken by Audrey and Elizabeth = 10 days ---- (1)
Time taken by Elizabeth and Samantha = 11 days ---- (2)
Time taken by Samantha and Sophia = 230% x 10 = 23 days ---- (3)

(1) + (2) + (3)
Audrey + Elizabeth + Elizabeth + Samantha + Samantha + Sophia → 10 + 11 + 23 = 44 days
Audrey + 2 (Elizabeth + Samantha) + Sophia → 44 days
Audrey + Sophia + 2 x 11 → 44 days
Audrey + Sophia → 44 - 22 = 22 days

More days to complete the project for Audrey and Sophia compared to Elizabeth and Samantha
= 22 - 11
= 11

Answer(s): 11
