Expected DA for Bank Employee from Aug'17 to Oct'17 may increase 20 to 22 slab

Now, today   i.e. on 30.06.2017, CPI for the month May'17 announced as 6345.60.

We are providing calculations of expected DA on the basis of three assumption as under :

1> As on 31.05.2017 figure was 6322.77.

1. As on 30.4.2017 figure was 6277.12.last quater average was 6261.91. now today's figure  6322.77 So difference is 6322.77-6261.91=60.86 i.e 15 slab already increase 
2. On assumptions that there would be increase of one point in CPI data in   the remaining months. In this situation the expected (tentatively) increase in DA Slabs would come to 20 slabs.(on this assumption the total tentatively revised DA slabs would be 476 i.e. 47.60%)

But present market trend and inflation basis Da may be increase 22 to 24 slab from August 2017
