The height of the tree was 56 inches.
We can calculate the percentage of a certain amount by :
Subtracting New - Original / New multiplied by 100
this implies it will be
75 - x / 75 × 100 = 25 %
7500 - 100 x = 1875
this implies 7500 - 1875 = 100 x
5625 = 100 x
Thus , On dividing both sides by 100 we get
56.25 = x
Now on rounding off this number we will get
56 = x
Thus the original height of the corn plant was 56 inches

300 ordered
80% of them are hi-def
so 80% of 300
is 0.8 x 300 = 240
240 of the ordered TV's are hi-def
or if you used the images
each inteval is 30 (because 10% of anything is its self minus a 0)
count up 8 intervals and count up by 30s
you get 240
