The average index number for the last 12 months is 191.5 and when we take the % of 191.5/115.77 is 165.4142 and when deduct 100 (merged D.A of 01.01.2006) the balance is 65.4142 and rounded figure is 65.
So we can expect the next dearness allowance, D.A from the month of January, 2012 as 65% (7% increases from last installment of D.A which is 58%)
If the basic pay of a government employee is Rs. 20000 and the basic transport allowance is 1200 he may get an increase in D.A of Rs. 1400 and an increase in Transport allowance of Rs. Rs. 84 and the total increase of monthly salary will be Rs. 1484.
Expected D.A (Dearness Allowance) next installment
AICPIN (IW) for the month of December, 2011 is 197
