Answer:
Assume face value of both bond be $ 1,000
A)price of a 3 year bond = (PVAF10%,3 * interest ) +(PVF10%,3 * Face value)
=(2.48685 * 50 ) +(.75131 * 1000)
= 124.34 + 751.31
= $ 875.65
B)Price of a 10 year bond = (PVAF10%,10 *interest) +(PVF10%,10 * Face value)
=(6.14457 *50) + (.38554 *1000)
= 307.23 + 385.54
= $ 692.77
c)Long term bonds are more sensitive to short term bonds .This is so because longer the duration ,higher is the risk .so when interest rate changes ,longer duration prices will fall more than by short term bonds.
