Pl refer my pf index no 937959. I received rs.17756/ on 22/07/17as arrear of pension. So far i was being paid pension @rs.3857/. My substantive salary at the time of vrs on 31st march 2001 was rs.13734/ on which rate i was paid vrs amount. (Adjusting allowance rs.550/+50%fpa rs.396/+basic pay rs.10880/+pqa & acting allowance rs.1908/). All others of same cadre have been paid much higher amount.
