In simple interest, the interest rate is
i=(10500-9000)/9000=16.67%
In compound interest, compounded monthly,
10500=9000(1+i/12)^12
=>
APR=12(10500/9000)^(1/12)-1
=11.155%
(effective interest is still 16.67%)

This is done that way because to avoid fluctuations in the curve while analyzing the curve.</span>
