- A, B and C can finish a job in 10, 12 and 15 days respectively. How long will they take together, and how should a payment of ₹4,500 be shared?
4 days. With total work 60 units, they do 6 + 5 + 4 = 15 units a day, so 60/15 = 4 days. Wages follow work done; they work the same days, so the ratio is 6 : 5 : 4: ₹1,800, ₹1,500 and ₹1,200.
