Let x be the <span>heights of a maple tree and y be the height of the cherry tree.
We know:
</span> $\frac{x}{y} = \frac{5}{2}$
<span>The new ratio is obtained like this:
</span> $\frac{x+20}{y-20} = \frac{3}{1}$ .
From the above equation we get $x= (y-20)\frac{3}{1} -20$ .
then $\frac{ (y-20)\frac{3}{1} -20}{y} = \frac{5}{2}$
Solving the above equation for y we get: $y=160$
So $x=400$
So the first tree is (400-160=240) more taller than cherry tree.
