Interest on income tax

consider following example:

Details for assessment yr 2011-2012 are as follows:

Total tax - 290000

TDS -    200000

Advance tax- 1st inst.:30000, 2nd inst.:30000, 3rd inst.:25000 (balance tax due:5000)

capital gain: NIL

Is one liable to pay interest on this amount i.e. Rs5000, under both sec 234B and 234C?If yes, then kindly compute interest on this amount(Rs5000) under both these sections, assuming one has to file tax before 31^st June. Thanks.
