Let, S1,S2,S3,S4 be the sums of A,B,C,D taking 3 of them at a time.
So, by the given data in the problem,it follows that :
S1+S2+S3+S4 = 4613+4961+5010+5099
=>S1+S2+S3+S4 = 19683....[eqn 1]
Now, Without the loss of generality we can assume
S1= A+B+C
S2= B+C+D
S3= C+D+A
S4= D+A+B
-------------------------------------------------------
adding the above terms we get,
S1+S2+S3+S4 = 3(A+B+C+D)
=>19683 = 3(A+B+C+D); [From [eqn 1] ]
=>(A+B+C+D)=(19683/3)
=>(A+B+C+D)=6561

So,the greatest term among them =sum of all four - sum of lowest three terms
So,the greatest term among them=6561-4613 = 1948.

So,the greatest term among them = 1948

So, the correct answer is : OPTION a)1948

=>(A+B+C+D)=(19683/3)
=>(A+B+C+D)=6561
=>the gretest term among them =sum of all four -lowest no of the series
=> 6561-1948
=>1948 is the answer

thanks, i understood the answer.
but i have one question, from where can i find this kind of question (i.e. source). i am preparing for TCS , ans for that i am solving their papers. i did not come across to any such question.

from where did you find this question!? let me know such question bank for new pattern of TCS aptitude.
