Answer:
16 Days.
Step-by-step explanation:
10 workers can finish the job in 15 days
1 worker will do the same job in 15x10= 150 days
one worker one day job = 1/150
6 workers 5 days job = 6x5/150= 1/5 ..(1)
8 workers 3 days job = 8x3/150= 4/25 ..(2)
Now 4 more workers joined after 8 days
Total workers now available 12.
Work remaining = 1 - 1/5- 4/25= 16/25
Remaining work completed by 12 workers in
150/12 x 16/25= 8 days …(3)
Total work was completed in
5 + 3 +8 = 16 days
Hence job was done in 16 days.
