Assume interest is I, bond's selling price is P

From the question: I=5000*8%=400 P*6.5%=I=400
So P=400/(6.5%)=6154

Answer is (E)

Let x be the bond's selling price

Given 6.5%(x) = 8%(5000)

6.5%(x) = 400

So x = 40000/6.5 > 6000

Hence choice E

Sale price= (8/6.5)*5000

Since 8/6.5 is larger than 1, so we know that the sale price is greater than 5000. Since you do not have a calculator, you need to estimate the result.
By looking at 8 divided by 6.5, we can estimate that the correct answer is either D or E. For the sale price to be equal to 6000, 8 divided 6.5 should be equal to 1.2, which is not the case and so the answer is E.
