Solution: The field will be harvested in approximately in 7 days.
Explanation:
Let the number of days be x in which the fields will completely harvested.
The farmer can harvest the wheat from 12 acres per day.
In x days he farmer can harvest 12x acres.
It is given that the farmer has 75 acres of wheat.
[tex]12x=75[/tex]
[tex]x=\frac{75}{12}[/tex]
[tex]x=6.25[/tex]
In 6th day the field will not harvested completely.
Therefore, the field will be harvested in approximately in 7 days.
