-30, -29, -28 ... ... 30, 31, 32, 33
31 + 32 + 33 = 96, So m is 33
Answer is Qnt B
31 + 32 + 33 = 96, So m is 33
Answer is Qnt B

\((-30) + (-29) + (-28) + .......... + m = 96\)
Since, the sum is positive - we will have \(m > 30\)
terms from \(-30\) to \(30\) will cancel each other
\((-30) + (-29) + (-28) + .......... + 28 + 29 + 30 + m = 96\)
\(31 ≠ 96\)
\(31 + 32 ≠ 96\)
\(31 + 32 + 33 = 96\)
Col. A: \(33\)
Col. B: \(34\)
Hence, option B
