Answer:
$630
Step-by-step explanation:
The computation of the interest revenue is shown below:
= Principal × rate of interest × number of months ÷ (total number of months in a year)
= $21,000 × 12% × (3 months ÷ 12 months)
= $630
The three month is computed from October 1 to December 31. We assume the books are closed on December 31
We simply apply the simple interest formula, So that the correct value of interest can be computed
Hence, all the things are considered for the computation part.
