The docu. is Rs.10000 posted on 01.01.2007
but while calculating the interest, it need to calculate interest like this
1. for the first 3000 no interest
2. from 3001 to 6000 calculate interest at 5%
3. from 6001 to 8000 calculate interest at 6%
4. for remaining amount it calculate at 7% defined in Interest rates.
How can we do this
