TIFR CSE 2014 | Part A | Question: 18
We are given a collection of real numbers where a real number $a_{i}\neq 0$ occurs $n_{i}$ times. Let the collection be enumerated as $\left\{x_{1}, x_{2},...x_{n}\right\}$ so that $x_{1}=x_{2}=...=x_{n_{1}}=a_{1}$ and so on, and $n=\sum _{i}n_{i}$ ... $\min_{i} |a_{i}|$ $\min_{i} \left(n_{i}|a_{i}|\right)$ $\max_{i} |a_{i}|$ None of the above

Please find the value of this limit
I have applied L'Hospital here. And result came up like this : $1 - \frac{1}{2} (y^{2} + y)^{-\frac{1}{2}} (2y+1)$ Then after applying limit value , result came as $-\infty$. Am I wrong ? Please correct me.
