If Salik and Amelia work together on a project, they will complete it in 10 days. If Amelia were to work with Maya on the same project, they will take a day longer. If Maya and Samantha work together, they will take 200% more time than Salik and Amelia. If Salik and Samantha were to work together, how many more days will they take to complete the project compared to Amelia and Maya working together?
Time taken by Salik and Amelia in percent = 100%
Time taken by Maya and Samantha = 100% + 200% = 300%

Time taken by Salik and Amelia = 10 days ---- (1)
Time taken by Amelia and Maya = 11 days ---- (2)
Time taken by Maya and Samantha = 300% x 10 = 30 days ---- (3)

(1) + (2) + (3)
Salik + Amelia + Amelia + Maya + Maya + Samantha → 10 + 11 + 30 = 51 days
Salik + 2 (Amelia + Maya) + Samantha → 51 days
Salik + Samantha + 2 x 11 → 51 days
Salik + Samantha → 51 - 22 = 29 days

More days to complete the project for Salik and Samantha compared to Amelia and Maya
= 29 - 11
= 18

Answer(s): 18
