Answer:
15
Explanation:
Simple interest is calculated thus; P×R×T ÷ 100
Where P is the principal, which is the bond in this case (1000)
R is the rate at which the interest will be paid per annum (3%)
T is the time in years at which the interest will be paid (6/12years or 0.5years)
Next step is to input the digits into the formula;
1000×3×0.5 / 100
Solving this, we have $15
Therefore, an interest of $15 will be received by John on 1000 bond every six months
