If Mason and Aaron work together on a project, they will complete it in 5 days. If Aaron were to work with Alexander on the same project, they will take a day longer. If Alexander and Ava work together, they will take 60% more time than Mason and Aaron. If Mason and Ava were to work together, how many more days will they take to complete the project compared to Aaron and Alexander working together?
Time taken by Mason and Aaron in percent = 100%
Time taken by Alexander and Ava = 100% + 60% = 160%

Time taken by Mason and Aaron = 5 days ---- (1)
Time taken by Aaron and Alexander = 6 days ---- (2)
Time taken by Alexander and Ava = 160% x 5 = 8 days ---- (3)

(1) + (2) + (3)
Mason + Aaron + Aaron + Alexander + Alexander + Ava → 5 + 6 + 8 = 19 days
Mason + 2 (Aaron + Alexander) + Ava → 19 days
Mason + Ava + 2 x 6 → 19 days
Mason + Ava → 19 - 12 = 7 days

More days to complete the project for Mason and Ava compared to Aaron and Alexander
= 7 - 6
= 1
