D1 and D2 can do a piece of work together in 16 days, D2 and D3 can do the same work together in 24 days, while D3 and D1 can do it together in 48 days. In how many days can all 3, working together, do 5/6 of the work?
\(\frac{31}{3}\ \text{days}\)
\(\frac{40}{3}\ \text{days}\)
\(\frac{35}{3}\ \text{days}\)
\(\frac{38}{3}\ \text{days}\)
In a job, Z1, Z2 and Z3 work for 8, 10 and 15 days, respectively. The ratio of the daily wages of Z1, Z2 and Z3 is 3 : 4: 4, respectively. If they receive ₹4,960 as total wages for the work done, then what is the combined share of Z2 and Z3 in the total wages received?
