Ans: Since, the sum of different integers is zero, we can guess that some of them will be negative and others positive; one of them can be zero also.
Also, we are to make the number of positive integers ‘least’ (or the number negative integers ‘most’), we can take the integers to be:
-9, -8, -7, -6, -5, -4, -3, -2, -1, 0, P
Where P is the single positive integer whose value would be (1+2+3+4+5+6+7+8+9). No need to find this value. Option (B) is the correct answer.
