On the first day, the tractor brigade plowed 30% of the area of the entire field, on the second – 75% of the rest, and on the third – the remaining 14 hectares. Find the area of the field.

Let’s say:
Let x be the part that was dug up in the second and third day, then:
x – 0.75 x = 14 (0.75 is 75%)
0.25 x = 14
x = 14: 0.25
x = 56 (ha is the field that was dug up in the second and third days)
56 * 100/70 = 80 ha (whole field)
Answer: 80
