If Rael and Samantha work together on a project, they will complete it in 10 days. If Samantha were to work with Victoria on the same project, they will take a day longer. If Victoria and Mason work together, they will take 60% more time than Rael and Samantha. If Rael and Mason were to work together, how many more days will they take to complete the project compared to Samantha and Victoria working together?
Time taken by Rael and Samantha in percent = 100%
Time taken by Victoria and Mason = 100% + 60% = 160%

Time taken by Rael and Samantha = 10 days ---- (1)
Time taken by Samantha and Victoria = 11 days ---- (2)
Time taken by Victoria and Mason = 160% x 10 = 16 days ---- (3)

(1) + (2) + (3)
Rael + Samantha + Samantha + Victoria + Victoria + Mason → 10 + 11 + 16 = 37 days
Rael + 2 (Samantha + Victoria) + Mason → 37 days
Rael + Mason + 2 x 11 → 37 days
Rael + Mason → 37 - 22 = 15 days

More days to complete the project for Rael and Mason compared to Samantha and Victoria
= 15 - 11
= 4

Answer(s): 4
