Together their contribution is (1/9 + 1/12 + 1/15)=1/3.829
Therefore, on every 3rd day their contribution total is 1/3.829
Therefore, on 9th day (it is Ratan's 3rd turn), total contribution = (1/3.829)*3 =0.783 Work
On 10th day (Ram's 4th turn) = (3/3.829 + 1/9) =0.895 Work
On 11th day (Ravi's 4th turn) = (3/3.829 + 1/9 + 1/12) =0.978 Work
Later work is finished by Ratan on 12th day.
Therefore, Ravi's contribution = (1/12)*4 =1/3rd proportion
