[SOLUTION] Find the APR, or stated rate, in each of the following cases
From \$8/Page

EAR=(1+APR/m)^m-1

where m=compounding periods

1.

0.111=(1+APR/2)^2-1

(1+0.111)^(1/2)=1+APR/2

Hence APR=[(1+0.111)^(1/2)-1]*2

=10.81%(Approx).

2.

0.12=(1+APR/12)^12-1

APR=[(1.12)^(1/12)-1]*12

=11.39%(Approx).

3.

0.097=(1+APR/52)^52-1

APR=[(1.097)^(1/52)-1]*52

=9.27%(Approx).

4.

EAR=e^APR-1

where e=2.71828

0.134=2.71828^APR-1

1.134=2.71828^APR

Taking log on both sides;

log 1.134=APR*log 2.71828

Hence APR=log 1.134/log 2.71828

=12.58%(Approx).
