3% increment = Rs. 639.90 i.e. Rs.640/- will be added with your B.P.
Now B.P. will be Rs. 21970/-
But you will not get your normal Annual increment on 01/07/2014. Next increment will be on 01/07/15.
***** Now you may give option to take your 10 years benefit on 01/07/2014. and annual increment on the same day.
1) Firstly, annual increment = Rs. 21970/-
2) Secondly 10 years of benefit = 3% increment = Rs. 659.10 i.e. Rs.660/- will be added on your B.P.
3) B.P. will be on 01/07/2014 =Rs. 22630/-
Next increment will be on 01/07/15.
Thanks a lot.
