If Ethan and Layla work together on a project, they will complete it in 12 days. If Layla were to work with Ella on the same project, they will take a day longer. If Ella and Salik work together, they will take 200% more time than Ethan and Layla. If Ethan and Salik were to work together, how many more days will they take to complete the project compared to Layla and Ella working together?
Time taken by Ethan and Layla in percent = 100%
Time taken by Ella and Salik = 100% + 200% = 300%

Time taken by Ethan and Layla = 12 days ---- (1)
Time taken by Layla and Ella = 13 days ---- (2)
Time taken by Ella and Salik = 300% x 12 = 36 days ---- (3)

(1) + (2) + (3)
Ethan + Layla + Layla + Ella + Ella + Salik → 12 + 13 + 36 = 61 days
Ethan + 2 (Layla + Ella) + Salik → 61 days
Ethan + Salik + 2 x 13 → 61 days
Ethan + Salik → 61 - 26 = 35 days

More days to complete the project for Ethan and Salik compared to Layla and Ella
= 35 - 13
= 22

Answer(s): 22
