Ashok can complete a work in 10 days if he works for 4 hours everyday. Bharath can complete the same work in 4 days and Charan in 8 days but have to work 8 hours and 7 hours a day respectively. If Bharath and Charan can complete another work in 7 days working for 4 hours a day, then how many days would Ashok take to complete the work if he works for 5 hours a day?

Let the work be 1120 units. SO A =28units/hour B=35units/hour C=20units/hour.Work2 = 28(35+20) units.so A does in (28 x 55) / (5 x 28) = 11 days.
