Answer:
5.8%
Explanation:
Current yield = 6.1%
Face value of bond = $500
Market price of bond = $475
Let the original coupon rate be CR
![Current\hspace{2}yield = \frac{Coupon\hspace{2}rate* Bond\hspace{2}face\hspace{2}value}{Market\hspace{2}price}*100](https://img.qammunity.org/2020/formulas/mathematics/middle-school/jczg4kks2mg717hmzikpz9n0fxtg8uq72l.png)
![6.1 = (CR*500)/(475)*100](https://img.qammunity.org/2020/formulas/mathematics/middle-school/gbpoidqltmzdmpe5qfd1u1rf31pbs39adt.png)
Multiply both sides by 475
![6.1 *475 = (CR*500)/(475)*100*475](https://img.qammunity.org/2020/formulas/mathematics/middle-school/yochulbkzxi68hoxa6ytngt5tw37b5s0wp.png)
Cancel out the 475's from the top and bottom of the right side
![6.1 *475 = CR*500*100](https://img.qammunity.org/2020/formulas/mathematics/middle-school/hzb5wjazbty02d34vv77byrsycq9g7m4qq.png)
![2897.5 = CR*50000](https://img.qammunity.org/2020/formulas/mathematics/middle-school/thovnb5yhf562fs95nxfdspt7yqd880lvv.png)
Flip the sides
![CR*50000 = 2897.5](https://img.qammunity.org/2020/formulas/mathematics/middle-school/tid9wcvawvktdx4m04x0jbm2nqshoboaq7.png)
Divide both sides by 5000
![(CR*50000)/(50000) = (2897.5)/(50000)](https://img.qammunity.org/2020/formulas/mathematics/middle-school/8nj6hjxb11nzgtx995g1bkvfhfyl7jw8l1.png)
Cancel out 50000 from the top and bottom of the left side

CR = 0.0579 * 100 [convert decimal into a percentage]
CR = 5.79 %
CR = 5.8% [rounded off to the tenth place]
