第二章 财务管理基础知识
1.FA=A×(F/A,5%,10) =10×12.578 =125.78
PA=A×(P/A,5%,10) =10×7.7217 =77.217
F=P×(F/P,5%,10) =100×1.6289 =126.89
不应投资该项目.
2. 100=A×(P/A,8 %,10)
A=100/6.7101=14.90
100=A×(P/A,2%,40)
A=100/27.3555=3.66
3. FA=20×(F/A,5%,5) =20×5.5256 =110.512
PA=20×(P/A,5%,8)- 20×(P/A,5%,3) =20×(6.4632-2.7232) =74.8
4.(1) F=1000×[ (F/A,5%,4)-1 ] =1000×(4.3101-1) =3310.1
P=3310.1×(P/F,5%,3) =3310.1×0.8638 =2859.26
(2) 3310.1=A×(P/A,5%,5)
A=3310.1/4.3295=764.55
(3) P=1000×(P/A,5%,3)+ 1200×(P/F,5%,4) + 1300×(P/F,5%,4)
=1000×2.7232+1200×0.8227+1300×0.7835=4728.99
(4)1000×(P/A,5%,3)=2723.2<3310.1
1000×(P/A,5%,3)+ 1200×(P/F,5%,4) =3710.44>3310.1
所以需4年
5.(1) EA=100×0.3+50×0.4+30×0.3=59
EB=110×0.3+60×0.4+20×0.3=63
Ec=90×0.3+50×0.4+30×0.3=56
σA = (100-59)2×0.3+(50-59)2×0.4+(30-59)2×0.3
=28.09
σB = (110-63)2×0.3+(60-63)2×0.4+(20-63)2×0.3
=34.94
σC = (90-56)2×0.3+(50-56)2×0.4+(30-56)2×0.3
=23.75
28.09
qA= ×100% = 47.61%
59
34.94
qB= ×100% = 55.46%
63
23.75
qc= ×100% = 42.41%
56
(2)A=8%*47.61%=3.81%
B=9%*55.46%=4.99%
C=10%*42.41%=4.24%
从风险来看,A最低,C其次,B最高;从风险收益率来看,A最低,C其次,B最高。投资者选c,喜欢冒险的投资者选B。
案例分析题
(1)2000=300×(P/A,i,10)
(P/A,i,10)=6.667
(P/A,8%,10)=6.710
(P/A,9%,10)=6.418
i=0.043/0.292+8%=8.15%
(2) 2000=230×(P/A,i,15)
(P/A,i,15)=8.696
(P/A,7%,15)=9.108
(P/A,8%,15)=8.559
i=0.0412/0.549+7%=7.75%
(3) 2000=210×(P/A,i,20)
(P/A,i,20)=9.524
(P/A,8%,20)=9.818
(P/A,9%,20)=9.129
i=0.294/0.689+8%=8.43%
(4) 2000=180×(P/A,i,25)
(P/A,i,25)=11.111
(P/A,7%,25)=11.654
(P/A,8%,25)=10.675
i=0.543/0.979+7%=7.55%
所以,选择25年的还款方式最有利。
2. (1)资产的总价等于房产、股票和现金25年后的终值即:
房产终值 =400 000
(F/P,3%,25) =837 520
股票终值=100 000
(F/P,9%,25)+8 000
(F/A,9%,25)(1+9%)
=1 600 902.72
现金终值=10 000 (F/P,5%,25)+2 000
(F/A,5%,10)( F/P,5%,15)
+10 000
(F/A,5%,15)=606 726.81
资产总价=房产终值+股票终值+现金终值=3 045 149.53
(2)首先从3 045 149.53中减掉捐赠的100 000元,实际上是要计算在20年的时间,以7%为利率每年的普通年金是多少。
