9's complement of a decimal number represented in 2421 code is easily obtained by replacing the 1s with 0s,and 0s with 1s,so 2421 code is called a self complementing code.
example-2421 of '2' is '0010',after replacing the 0s with 1s and 1s with 0s we
get '1101' which is the 2421 of '7'(9s complement of 2 is 7). Thus 2421 code is self complementary.
