Answer:
$6,000
Explanation:
Interest calculation : June 30 - December 31
Time frame between the two dates is 6 months, thus charge half year`s interest.
Interest calculation = $120,000 x 10 % x 1/2 = $6,000
therefore,
The  interest revenue that would be recorded for the year ending December 31 if the sale was made on June 30 is $6,000.
