If an investor’s required return is 12 percent, the value of a 10year maturity zerocoupon
bond with a maturity value of $1,000 is closest to:
A. $312.
B. $688.
C. $1,000.
D. $1,312.
Could you try to calculate the answer? For me it looks like there is a mistake..

A
I/Y = 12
N = 10
FV = 1000
CPT PV = 321.97
A is closest.

joehogue

calculate zeros as if they are semi annual.
so I/Y 6
N 20
FV 1000
PV = 311.80
