sir, In your question it is written that in 1,00,000 amount after deducting 30,000 as commission rest made 70,000 ok now TCs is deducted 1% it become 700 and also 20,000 is sale return 

There fore 70000-20000=50000 and tcs will be 500 as 1%

so In my opinion balance amount must be 45500 (i.e 50000-500)
