The area covered by corn is x

The area covered by wheat is (x+480)

After 80% of wheat was collected, the new area was:

20/10 (x+480)

=1/5 (x+480)

After 25% of the corn was collected, the new area was:

75/100x

=3/4x

New area equation will be:

(3/4) x=1/5 (x+480) + 300

(3/4x) = (1/5) x+96+300

solving for x we get:

11/20x=396

x=720

thus the original area of corn was 720 acres

Original area of wheat was 720+480=1200 acres
