basis of assessment question

Hi. this is a question from kaplan text:

new trade commences: 1 jun 2011. year end is 30 apr.
profits are:

to 30 apr 12 – 11,000
to 30 apr 13 – 18,000
to 30 apr 14 – 22,000

up till year 3, ie for tax years 11/12, 12/13, 13/14, my calculations are correct.

i am unable to understand year 4: 14/15

this is what i am doing:

is there a period end in this year? the answer is YES. it is 30 apr 14.
is this period =12, <12 or >12 months? the answer is =12 months
therefore, the basis of assessment is CYB
basis period: 1 may 14 – 30 apr 15

but we dont have data to 30 apr 15.

the answer for year 4 is 22,000 cyb.

and in my workings, i do get till the cyb portion…

can u pls explain where i am going wrong?

thank u
