under 234 A interest - NIL
under 234 B interest is payable if the advance tax paid is less than 90% of tax payable @ 1% till the date of payment.
Tax liability = 120898
90% of Tax payable = 120898*90% = 108808.20 = 108808
But advance tax paid = 57409
Interest to be paid under 234B = (108808-57409)*1%*3/12 = 51399*1%*3/12 = 128.
Under 234C interest is payable if advance tax paid per quarter is less than advance tax payable per qurater @ 1%
IInd Quarter - {(120898*30%)-12823}*1%*3/12 = 23466*1%*3/12 = 58.616 = 59
IIIrd Quarter - {(120898*60%)-25953}*1%*3/12 = 46586*1%*3/12 = 116
IVth Quarter - {(120898*100%)-57409}*1%*3/12 = 63489*1%*3/12 = 158.72 = 159
Total interest u/s 234C = 59+116+159 = 331
Total Interest u/s 234A,234B,234C = 0+128+331 = 459
