Loan note

Hi Mr Mike, I have two important questions here.

Question has been taken from 3 June exam 2015

Trial balance relates to Clarion as at 31 March 2015

8%loan note -20000(credit side)
Operating lease payments-2000(debit side)
Suspense account-5800(debit side)

Income tax rate 25%
Notes.
On 31 March 2015, one quarter of the 8% loan notes were redeemed at par and six month’s outstanding loan interest was paid.The suspense account represents the double entry corresponding the the cash pay for the capital redemption and the outstanding interest.

Clarion renewed an operating lease on a property on 1 April 2014.The operating lease payments represent an annual pay(in advance) of $1 million and a lease premium of $1 million. The leases is for four years and operating lease expenses should be included in cost of sales.

Could you explain it to me?
Elimination of suspense account
Cash cost of loan note redemption (20000*25%)-5000
6 month’s interest on loan note (20000*8%*6/12)—800
overall 5800

Surely the 6 months’ outstanding loan interest relates only to the $5,000 loan that was redeemed so that $800 needs to be recalculated as

6 month’s interest on loan note (20000/4*8%*6/12) = 200

I did not understand it Mr Mike,

Cash cost of loan note redemption (20000*25%)-5000-why 25%?
6 month’s interest on loan note (20000*8%*6/12)—800

6 month’s interest on loan note (20000/4*8%*6/12) = 200-confused when I saw 800 ?

looks like puzzle
