Let's take the value of a stock in \(2007 = 100\)
\(2007\) to \(2008 : 30\)% increase
Value in \(2008 = 130\)
\(2008\) to \(2009 : 10\) % decrease
Value in \(2009 = 0.9 * 130 = 117\)
Total increase is \(17\)%
Answer C
\(2007\) to \(2008 : 30\)% increase

\(2008\) to \(2009 : 10\) % decrease
Value in \(2009 = 0.9 * 130 = 117\)
Total increase is \(17\)%
