If Elijah and Samuel work together on a project, they will complete it in 8 days. If Samuel were to work with Natalie on the same project, they will take a day longer. If Natalie and Mia work together, they will take 100% more time than Elijah and Samuel. If Elijah and Mia were to work together, how many more days will they take to complete the project compared to Samuel and Natalie working together?
Time taken by Elijah and Samuel in percent = 100%
Time taken by Natalie and Mia = 100% + 100% = 200%

Time taken by Elijah and Samuel = 8 days ---- (1)
Time taken by Samuel and Natalie = 9 days ---- (2)
Time taken by Natalie and Mia = 200% x 8 = 16 days ---- (3)

(1) + (2) + (3)
Elijah + Samuel + Samuel + Natalie + Natalie + Mia → 8 + 9 + 16 = 33 days
Elijah + 2 (Samuel + Natalie) + Mia → 33 days
Elijah + Mia + 2 x 9 → 33 days
Elijah + Mia → 33 - 18 = 15 days

More days to complete the project for Elijah and Mia compared to Samuel and Natalie
= 15 - 9
= 6

Answer(s): 6
