Reg merger scale 500055006500-10500 what will 1 st ACP?

pre-revised scales of 5000-8000 and 5500-9000 merged given grade pay 4200 and 6500-10500 and 7450-11500 merged given grade pay 4600 so,the question is what is grade pay on 1st ACP ?

The answer is that as on 01-01-2006 whatever ACPS earned will be ignored if earned in pre revised scales thus any one completes 12 years between 01-01-2006 and 31-08-2008 be allwed to get 4600 grade pay if they were recruited in 5000-8000 scale.
