Question

The survey for analyzing two trees Oak and Pine has been conducted and the results obtained are shown in a bar graph. What is the percentage increment in the number of Oak trees from the year 2005 to 2011?

• A. 5 %
• B. 10 %
• C. 12.5 %
• D. 15 %

Answer 1

The correct option is C

12.5 %

In 2005, number of Oak trees = 40

And in 2011, it is = 45.

Now, basically, percentage increment from A to B is $\frac{A-B}{A}\times 100$

$Sothepercentageincrementfrom2005to2011is$

$\Rightarrow \frac{45-40}{40}\times 100=\frac{1}{8}\times 100=12.5$%
