After working for 8 days, Anil finds that only 1⁄3 of the work has been done. He employs Rakesh who is 60 % efficient as Anil. How many more days will Anil take to complete the job? Choose the correct choice: A) 15 days B) 12 days C) 10 days D) 8 days E) None of these
In 8 days, Anil does = 1⁄3 rd work   ∴ in 1 day, he does = 1⁄24 th work.   ∴ Rakesh’s one day’s work   = 60% of 1⁄24 = 1⁄40 th work.   Remaining work = 1 - 1⁄3 = 2⁄3   (Anil and Rakesh)’s one day’s work   = 1⁄24 + 1⁄40 = 1⁄15 th work.   Now, 1⁄15 th work is done by them in one day.   ∴ 2⁄3 rd work is done by them in 15 × 2⁄3 = 10 days   Answer 10 days
