Answer:
$1,535.21
Step-by-step explanation:
Given:
Amount borrowed = $60,000
Time period = 12 years
rate of interest = 8%
Sinking fund is created to pay off the amount borrowed after 12 years. It is required to compute periodic payments:

where r is 0.08
m = number of payments per year which is 2 (since it's semi annual)
n = number of years
A is amount of sinking fund
Substitute these values in the above formula:

= $1,535.21
Therefore, $1,535.21 is paid into the fund each period.
