|Please someone explain this logic.|

|I can't understand the logic in a given options.
Please any one explain me the logic.

|A=1100 AND B=1001
SO both having equal number of one's and zero's but the value is differs. A is greater compare to B but it's having equal no of one's (A>B=1) same holes good for next statement but considering zero's A value is smaller compare to B but its having equal number of zero's (A<B=0) and finally both are equal (A=B=0) zero indicate hr (A-B) but in the form of number of ones and zero's present both are equal so zero.

|As far I am thinking its a comparator which compares two numbers.
A is 1100 (12) , B is 1001 (9). A>B (TRUE so 1) , A<B (FALSE so 0) , A=B (FALSE so 0).
Well I am not sure whether I am following the correct logic.

|Yes, sudeep give correct explanation.|
|Sanjiya said: (Apr 1, 2013)|
|A = 1100,(12).
B = 1001,(9).
1 is represent true.
0 is represent false.
A>B=1, A<B=0, A=B=0;
True, False, False.

|What is the correct answer?|
|Manowar said: (Aug 7, 2016)|
|You are right @Sudeep.|
|Divya Chaudhary said: (Nov 4, 2016)|
|The logic behind the ansswer is:
There can be three cases : number A is greater than number B,or less than B or equal to B.
Now,in question A=1100 whose decimal equivalent is 12 and B=1001 whose binary equivalent is 9.
So case1 is true, and we are using 1 for true and 0 for false.so combining three cases to giveanswer we get,
A > B = 1,A < B = 0, A = B = 0.

|Thanks for your explanation @Sanjiya.|
|Sachin said: (Aug 17, 2017)|
|You give a simple explanation easy to understand. Thanks @Sudeep.|

|You are right, thanks for the explanation @Sudeep.|

|I am not getting the solution. Anyone help me to get it.|
|Vishaka said: (Feb 21, 2018)|
|It's a bitwise comparison so A=B=1 , A>B=1,A<B=0.
according to my knowledge,
1st-row A=B, 2nd-row A>B, 3rd-row A=B, 4th-row A=B.
E is equal, G is greater.
