Answer:
The second year's interest expense would have been less.
Step-by-step explanation:
After paying the first installment, the outstanding payable balance would be $500000, therefore the the interest in the second year would be lower than $30000
If the annual cash payment would have been less, the amount paid under instalment would include interest payment and the repayment principle which would have been more than $30000 of interest expense
If the first year's interest expense would have been higher under both the methods, the amount outstanding at the beginning for interest calculation would be $500000 and interest at 6% would have been same for first year
Lastly, the effective interest rate would have been lower
