The two tabs are not a decoration. A salaried file and a business file are read differently by the same bank: one is proved by a salary slip and ends at retirement, the other by tax returns and needs the business to have a history. Everything here is your own figure — we fill in no bank's rate.
This is not an approval. A bank also weighs your credit record, your employer or your trade, the insurance it will add, its own processing fee, and whether it will lend on that particular property at all — banks in Pakistan rarely finance a bare plot.
