Original variant: coupon-bond price projected from a zero-coupon calibration
A ten-year zero-coupon bond with face 20,000 sells for 12,000. A second ten-year bond has face 15,000, pays 4% annual coupons, and has the same yield. Calculate the second bond's price.
- A
12,900.33 - B
13,579.30 - C
14,258.26 - D
14,937.23 - E
15,616.19
Answer and calculation
The zero price implies annual yield 5.2410%. Pricing the second bond's ten coupons and redemption at that yield gives 13,579.30, choice B.

Setup
Recover the common annual yield from the zero-coupon price and face.

Model
Price the coupon bond using annual coupon 600 and face 15,000.
P=600a10∣i+15000(1+i)−10 Compute
