ISI2021-MMA: 7
Let $S$ be a set of $n$ elements. The number of ways in which $n$ distinct non-empty subsets $X_{1}, \dots, X_{n}$ of $S$ can be chosen such that $X_{1} \subseteq X_{2} \dots \subseteq X_{n},$ is $\left( \begin{array} c n \\ 1 \end{array} \right) \left( \begin{array} c n \\ 2 \end{array} \right) \dots \left( \begin{array} c n \\ n \end{array} \right)$ $1$ $n!$ $2^{n}$

ISI2021-MMA: 15
A straight line passes through the intersection of the lines given by $3x – 4y + 1 = 0$ and $5x + y = 1$ and makes equal intercepts of the same sign on the coordinate axes. The equation of the straight line is $23x – 23y + 11 = 0$ $23x – 23y - 11 = 0$ $23x + 23y + 11 = 0$ $23x + 23y – 11 = 0$

Doubt:
Let “m” be the number of edges, “n” the number of vertices and “k” the number of connected components of a graph G. Prove that: $\left ( n-k \right )\leq m\leq \frac{\left ( n-k \right )\left ( n-k+1 \right )}{2}$ Why least number of edges are $\left ( n-k \right )$ and Why most number of edges are $\frac{\left ( n-k \right )\left ( n-k+1 \right )}{2}$ ? What is the idea behind this prove?
