Question

If a farmer wants to plough a farm field on time, he must plough 120 hectares a day. For technical reasons he ploughed only 85 hectares a day, hence he had to plough 2 more days than he planned and he still has 40 hectares left. What is the area of the farm field and how many days the farmer planned to work initially?

Answer 1

the farmer planned to have the work done in 6 days, and the area of the farm field is 120 times 6 = 720 hectares.
