Presently I am working for Indian Railway's as Executive Director). I completed my degree in Civil Engineering in 1980 and joined Indian Railway's in 1983. My favorite hobby is Number Recreations. I am working with pleasure on this hobby since 1978, when my first paper "Miracles of Last Digit" was published in Indian magazine. Since then I have done lot of work on number recreations, some of which are not yet published. My contributions have been published in International journals and books including David Well's " Penguin Dictionary of Curious and Interesting Numbers". I am Co-author of a book "Civil Engineering through objective type questions" . I am very much interested in trying/developing different algorithms/code using different programming languages like Fortran, c++, Pascal , Ubasic, Mathematica , GP_Pari, etc. so as to reduce the computing time.
