Because it is an existing single entry commencing double entry thats why everything is included such as gst because they need to be debited and credited for the double entry system which is why gst is debited in the sample paper. question 4 paiad i got 6000 i think and 4800 incurred please tell me im correct
I think you didn't read the question properly. It asks for calculation of advertising paid/expense for the
year ended June 2012. This means you have to calculate 12 months of payments and expenses.
It's only 2 marks so this one should have been easy.
Cash Paid of $1200 for July 1 2011 to Aug 30 2011 = $1200*2 = $2400
Cash Paid of $1440 ($1200*1.2) for September 1 2011 to June 30 2012 = $1440*10 = $14400
Add them up and you'll get $16800
For Advertising expense, don't let the payment date confuse you it's just the date that they prepaid for the month ahead (eg paid $1440 on 20 Feb 2012 for a months worth of advertising between 1 March 2012 to 31 March 2012), so you don't need to factor in 20/30 days or whatever.
For July, August and September, you will incur $1200 advertising expense each month, and $1440 for every month after that
$1200*3 + $1440*9 = $16560
