If Andrew and Noah work together on a project, they will complete it in 12 days. If Noah were to work with Raeann on the same project, they will take a day longer. If Raeann and Aubrey work together, they will take 50% more time than Andrew and Noah. If Andrew and Aubrey were to work together, how many more days will they take to complete the project compared to Noah and Raeann working together?
Time taken by Andrew and Noah in percent = 100%
Time taken by Raeann and Aubrey = 100% + 50% = 150%

Time taken by Andrew and Noah = 12 days ---- (1)
Time taken by Noah and Raeann = 13 days ---- (2)
Time taken by Raeann and Aubrey = 150% x 12 = 18 days ---- (3)

(1) + (2) + (3)
Andrew + Noah + Noah + Raeann + Raeann + Aubrey → 12 + 13 + 18 = 43 days
Andrew + 2 (Noah + Raeann) + Aubrey → 43 days
Andrew + Aubrey + 2 x 13 → 43 days
Andrew + Aubrey → 43 - 26 = 17 days

More days to complete the project for Andrew and Aubrey compared to Noah and Raeann
= 17 - 13
= 4

Answer(s): 4
