Pooja and Ritu can do a piece of work in (120/7) days. If one day work of Pooja be three fourth of one day work of Ritu, find in how many days each will do the work alone

Dear Student,

Pooja and Ritu can complete a peice of work in 1207 days.The amount of work Pooja and Ritu complete in a day = 11207                                                                                 = 7120Let one day work of Ritu be x.Then one day work of Pooja = 34x.Total work in one day = x+3x4=7x4=71207x4=7120x=4120x=130.Therefore,Amount of work done by Ritu in one day = 130Number of days in which Ritu alone can complete the work =1130 =30.Amount of work done by Pooja in one day = 34×130=140Number of days in which Pooja alone can complete the work =1140 =40.So Ritu can complete the work alone in 30 days and Pooja can completethe work alone in 40 days.

Regards.
