Answer:
4%
Explanation:
Interest included in $918000 is for six months from 10/1/18 to 4/1/12.
Interest for first three month period from 10/1/18 to 31/12/18 = $9000.
This implies that :
Interest from 1/1/19 to 4/1/19 = $9000.
Principal amount excluding interest due:
= Baker's obligation amount - Accrued interest - Accrued interest
= $918,000 - $9,000 - $9,000
= $900,000
Interest rate:
= [($9,000 × 12/3) ÷ 900000] × 100
= 4%
