Respuesta :
112+8 each day
112:8=14 so for each 14 days they had 8 acres extra until they finish early 1 day so they did not had to work the 15th day.
Since 15 days were scheduled with 112 each day they plough 112•15=1,680 acres
112:8=14 so for each 14 days they had 8 acres extra until they finish early 1 day so they did not had to work the 15th day.

Answer: The farmers have to plough 1680 acres of land.
Step-by-step explanation:
Let the expected time to complete the plowing be 'x'.
In x days, a group of farmers had to plough = 112 acres
According to question, on exceeding the schedule by 8 acres per day, the farmers finished plowing one day earlier than expected.
So, New time = x-1
Number of acres of land becomes
[tex]112+8=120\ acres[/tex]
So, According to question, it becomes,
[tex]112\times x=120\times (x-1)\\\\112x=120x-120\\\\120=120x-112x\\\\120=8x\\\\x=\frac{120}{8}=15[/tex]
So, Total acres of land the farmers have to plough is given by
[tex]15\times 112=1680\ acres[/tex]
Hence, the farmers have to plough 1680 acres of land.
