If on inquiry regarding the sum due the Collector is of opinion that the sum deposited is the sum rightly due under the mortgage, he shall, unless he dismisses the petition under section 10, make an order as laid down in clauses (a), (b), (c) and (d) of section 6 of this Act, but if he is of opinion that a sum larger than the sum deposited should be deposited by the petitioner, he shall, unless he dismisses the petition under section 10, fix a period not exceeding 30 days within which the petitioner shall deposit the difference, together with any further sum which may be due on account of interest upto the date of the deposit. If the petitioner makes such deposit within such period or such further period not exceeding 30 days, as the Collector may fix, the Collector shall make an order as laid down in clauses (a), (b), (c) and (d) of section 6 of this Act.
If the petitioner fails to make such deposit within the period fixed, the Collector shall dismiss the petition.
