A correction.

Dear shri sahni, 

with ref to your mail seeking a specimen of our calculation sheet , I have since got the point raised thy you in regard to my own case checked by our calculation expert Shri. M Arunachalam. 

He confirms that figures in my example should read : existing pension 22907. Increased 24057(not 23482 as mentioned in my earlier circular .)
Net increase therefore is 1150.

Thanks for your pointing out the error and
with regards,

GNSridharan
