### Step 1: Calculate the Annual Coupon Payment
C = 0.053 \times 1687
C = 89.411 \text{ EUR}
### Step 2: Calculate the Present Value of the Annuity
PV_{\text{annuity}} = 89.411 \times \left(\frac{1 - (1 + 0.067)^{-10}}{0.067}\right)
PV_{\text{annuity}} = 636.79 \text{ EUR}
### Step 3: Calculate the Present Value of the Lump Sum
PV_{\text{lump sum}} = \frac{1687}{(1 + 0.067)^{10}}
PV_{\text{lump sum}} = 882.00 \text{ EUR}
### Step 4: Calculate the Total Present Value of the Bond
PV_{\text{total}} = PV_{\text{annuity}} + PV_{\text{lump sum}}
PV_{\text{total}} = 636.79 + 882.00
PV_{\text{total}} = 1518.79 \text{ EUR}
### Answer:
The total present value of the bond, which represents how much you should be willing to pay for it given a comparable investment yield of 6.7% per annum, is approximately 1518.79 EUR.
