20. The percentage change from 2005 to 2010 is ...
(60 -20)/20 × 100% = 2 × 100% = 200%
One might compute an average rate of change per year of ...
200%/(5 yr) = 40%/yr
_____
<em>Additional comment</em>
As with any statement of percentage, you need to be very clear about what the base is.
Here, 100% is the number of farms in 2005, so an increase of 40% per year is an increase by 40% of the number in 2005. That is very different from 40% of the number in the previous year, which is how an annual percentage increase is usually interpreted. (The average annual rate of change is closer to 24% with respect to the previous year's number.)
<span>the number of trees in the garden = x
</span><span>coconut trees = 0.6x
</span><span>mango trees = 0.6x * 0.25 = 0.15x
</span><span>apple trees = 0.15x * 0.2 = 0.03x
0.03x = 1500
x = 1500/0.03
x = 50 000 </span>← <span>the number of trees in the garden.</span>
