1.	On subtracting (01010)2 from (11110)2 using 1’s complement, we get ____________(a) 01001(b) 11010(c) 10101(d) 10100I have been asked this question in examination.Question is taken from 1’s, 2’s, 9’s & 10’s Complements in section Number System and Codes of Digital Circuits
Answer» Right option is (d) 10100 For explanation: STEPS For Subtraction using 1’s complement are: -> 1’s complement of the subtrahend is determined and added to the minuend. -> If the result has a CARRY, then it is dropped and 1 is added to the last bit of the result. -> Else, if there is no carry, then 1’s complement of the result is FOUND out and a ‘-’ sign preceeds the result.
