Explanation:
1.
When note is issued, liability is credit by the notes value and cash is credited.
2.
The adjusting entry is prepared 3 months after the note is issued so the 3 month's interest on note relates to 2015 and it should be recorded as expense and as it is payable at maturity so interest payable is credited.
3 month interest = 39.2 * 0.08 * 3/12 = 0.784million
3.
The note and interest will be payable that was accrued along with the remaining 9 months interest. Total interest is 39.2 * 0.08 = 3.136million
