admin A house was painted in 12 days by 5 men. How long will it take 3 men to pain the same house? A: 20 days B: 24 days C: 18 days D: 15 days
BB23 If the house is painted by 5 men in 12 days. Then, work done by 1 man in a day = 1/(12 x 5) = 1/60 Work done by 3 men in 1 day= (1/60) x 3 = (3/60) Now, number of days = 60/3 = 20 days
