ITR-4 queries for a consultant

I have part of my income from business and profession (IT consultant). I need help on how I fill Part BS, P&L and Schedule BP of ITR4
Here are the facts -
I received Rs 52500 from the company I was working for.
Of this I incurred expenses of Rs 12500.
TDS was approx Rs 5408.

I am filling ITR4 for the above as follows:
Part BS:
6.d Amount of cash balance : (52500-12500) = 40000
All other fields are 0 in Part BS

Part P&L:
51.a Gross receipts 52500
b. Gross profit 12500
c. Expenses 12500
d. Net profit (auto) 40000
All other fields are 0 in Part P&L

Schedule BP:
A.1 Profit before tax as per profit and loss account (item 43  or item 51d of Part A-P&L ) 40000 (from 51d)
A.37 Net Profit or loss from business or profession (same as above in 36 except in case of special business, after applying rule 7A, 7B or 7C) 40000
All other fields are 0 or auto generated in in Schedule BP.

Am I doing the right thing?
Thanks in Advance,
Amol
