Answer:
(Fatwa: 1603/1520=D/1429)
In November 2007, your amount increased from 15000 to 45000, so in November 2007 you must have given the Zakah of total 45000. Likewise in November 2008, you will have to give Zakah of total amount whether it increases or decreases (if it is equal to nisab). Your Zakah year shall complete in November; therefore you should clear your accounts in November.
