    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
