Answer» Correct Answer - Option 3 : 1/8 Given: A can do a piece of work = 24 days B can do a piece of work = 12 days Concept used: Total work = LCM Formula used: Efficiency = (Total work)/(Total time) Both can do same in a day = total efficiency ÷ total work Calculations: Total work = LCM = 24
Total work completed in one day = 1 + 2 = 3 Work done by A and B together in one day = 3/24 = (1/8)th of total work ∴ A and B can do (1/8)th of total work in one day together |
