A, B and C can complete a work in x, 1.5x and 2x days respectively. If they complete the work together, in what ratio should they be paid?
Elementary MathematicsTime and Work
- A2 : 3 : 4
- B6 : 4 : 3
- C3 : 2 : 1
- D4 : 3 : 2
Explanation
Payment is proportional to work rates, which are the reciprocals of the times: 1/x : 1/(1.5x) : 1/(2x) = 1 : 2/3 : 1/2. Multiplying by 6 gives 6 : 4 : 3 (B).
