Let x be the <span>heights of a maple tree and y be the height of the cherry tree.
We know:
</span>
<span>The new ratio is obtained like this:
</span>
.
From the above equation we get
.
then
Solving the above equation for y we get:
So
So the first tree is (400-160=240) more taller than cherry tree.
