Answer:
chinese will complete work in 36 Days
Indian will complete work in 18 days
Step-by-step explanation:
Let say Indian 1 day work = I
& Chinese one day work = C
4 indians and 4 Chinese can do a piece work in 3 days
=> Work done = 3 * ( 4I + 4C) = 12I + 12C
2 indians and 5 Chinese can finish it in 4 days
=> Work Done = 4 * (2I + 5C) = 8I + 20C
12I + 12C = 8I + 20C
=> 4I = 8C
=> I = 2C
Work done = 12(2C) + 12C = 36C
chinese will complete work in 36 Days
36C = 18 * (2C) = 18I
Indian will complete work in 18 days
