Question

Aravind can do a work in 24 days. mani can do the same work in 36 days. aravind, mani and hari can do a work together in 8 days. in how many days can hari alone do the work?

Answer 1

Arvinds + Mani's 1 day work = [ (1/24)+(1/36)]  [Arvind + Mani + Hari] 1 day work = (1/8) Haris 1 day work = (1/8) - [ (1/24)+(1/36)]= (1/18) So Haris total work in days = 18/1 = 18days
