Cash reduce

Dear all,

                 I work in a small private firm. I faced a problem for the assessment year 2011-12. The Balance Sheet shows that I have cash in hand near Rs.2,50,000/- but I need to reduce it to Rs. 30,000/- but the profit can not be reduced as it will be below 8% then. Plz suggest me how can I reduce the Cash without affecting my Gross Profit. Thank you.
