Ratio of the efficiencies of A, B and C is 2 : 5 : 3 Let the efficiency of A, B and C are 2x, 5x and 3x respectively Together they can complete the work in 27 days.
|
Total work = 27 × (2x + 5x + 3x) = 270x 4/9th part of total work Time required by B and C to complete 4/9th of total work = 120x/8x = 15 days |
