Dattaraya Ramchandra Kaprekar was born at Dahanu near Bombay. He discovered the shortest possible routes to solve mathematical problems. In 1927, he won the wrangler R. P. Paranjpe Mathematical Prize for an Original Piece of work in mathematics. He discovered 'Kaprekar Constant' in 1946. It is the number "6174". The constant 6174 is arrived at and this number then generates itself into one set of numbers called "self numbers" that is also known by his name. Kaprekar passed away in 1988.
