Answer:
Chinese will take 36 Days to complete work
Indian will Take 18 days to complete the Work
Step-by-step explanation:
Let say one Indian's 1 day work = I
& Chinese 1 day work = C
4 Indians and 4 Chinese can do a piece of 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
Total Work Done = 12(2C) + 12C = 36C
=> Chinese will take 36 Days to complete work
36C = 18 * 2C = 18 I
=> Indian will Take 18 days to complete the Work
