ATQ, we can say that Time taken by Anmol = 30 days Time taken by Bineet = 45 days (Since, Bineet is working double in 90 days) Time taken by Chintu = 60 days Let the total work be done by them is 180 units. Anmol’s one day work = (180/30) = 6 units Bineet’s one day work = (180/45) = 4 units Chintu’s one day work =(180/60) = 3 units Hence, the Amount earned by Anmol is = (2600/13) x 6 = Rs.1200
