Assume total work = LCM (22, 33) = 66 If the entire work is 66 units, Vijay can complete 3 unit per day, and Sanjay can complete 2 unit per days In 5 days, Vijay completes 15 units and got Rs.1650 i.e. Rs.110 per unit. Remaining work = (66 – 15)unit = 51 unit ∴ Sanjayearning = Rs.51 × 110 = Rs. 5610
