A50+I/200
B50+3I/100
C50+I/40
D100+I/50
E100+3I/100
Last year a certain bond with a face value of $5000 yielded 8 percent of its face value in interest .If that interest was approximately 6.5 percent of the bond's selling price,approximately what was the bond's selling price?
A 4063
B 5325
C 5351
D 6000
E 6154
1,Formular should be:2%l+(100+1%)/2=50+l/40
So,choose C
2,Selling price = 5000*8%/6.5% = 6153.85
So,the answer is E
