问题如下：
The detailed information of bond X and bond Y can be described as:
Coupon rate of bond X is 6%, and that of the bond Y is 8%;
Both of the bonds have the maturity of 3 years;
The price of bond X is 102, and the price of bond Y is 110.
We know that interest is paid annually, which bond has a lower yield-to-maturity?
选项：
A.Bond Y
B.Bond X
C.The yield-to-maturity of X and Y are equal
解释：
A is correct.
Bond X: N=3; PV= -102; PMT=6; FV=100; → I/Y=5.26
Bond Y: N=3; PV= -110; PMT=8; FV=100; → I/Y=4.37
老师，您好！请问这道题计算的结果为什么和以下结论不一致呢？
bond selling at discount:coupon rate＜yield to maturity
bond selling at premium:coupon rate＞yield to maturity
