If Andrew and Mia work together on a project, they will complete it in 7 days. If Mia were to work with Wyatt on the same project, they will take a day longer. If Wyatt and Ava work together, they will take 200% more time than Andrew and Mia. If Andrew and Ava were to work together, how many more days will they take to complete the project compared to Mia and Wyatt working together?
Time taken by Andrew and Mia in percent = 100%
Time taken by Wyatt and Ava = 100% + 200% = 300%

Time taken by Andrew and Mia = 7 days ---- (1)
Time taken by Mia and Wyatt = 8 days ---- (2)
Time taken by Wyatt and Ava = 300% x 7 = 21 days ---- (3)

(1) + (2) + (3)
Andrew + Mia + Mia + Wyatt + Wyatt + Ava → 7 + 8 + 21 = 36 days
Andrew + 2 (Mia + Wyatt) + Ava → 36 days
Andrew + Ava + 2 x 8 → 36 days
Andrew + Ava → 36 - 16 = 20 days

More days to complete the project for Andrew and Ava compared to Mia and Wyatt
= 20 - 8
= 12

Answer(s): 12
