Assuming no efficiency is lost or gained from working together, how many weeks would it take Common, working alone, to drop a full-length platinum LP?

(A) 3 and 1/3 weeks
(B) 3 weeks

Given the information, Kayne's one-week work = 1/5 and Common's one-week work = 1/x;

Thus, we have 1/5 + 1/x = 1/2 => x = 10/3 weeks = 3 and 1/3 weeks

The correct answer: A

Hope this helps!

1/5 + 1/X = 1/2
2X + 10 = 5X

10 = 3X

X = 10/3 = 3 ⅓ weeks
