R K Bansal Solutions for Chapter: Set Concepts, Exercise 2: EXERCISE 13(B)

Examine the following set are the empty set:
$\mathrm{P}=\{\mathrm{x}:3\mathrm{x}=0\}$

If $\mathrm{n}( \mathrm{A})=\mathrm{n}( \mathrm{B})$, then $\mathrm{A}$ and $\mathrm{B}$ are equivalent sets.

If $\mathrm{B}=\{\mathrm{x}:\mathrm{x}+4=4\}$, then $\mathrm{B}$ is the empty set.

The set of all points in a line is a finite set.

The set of letters in your Mathematics book is an infinite set.

If $\mathrm{M}=\{1, 2, 4, 6\}$ and $\mathrm{N}=\{\mathrm{x}:\mathrm{x}$ is a factor of $12\}$, then $\mathrm{M}=\mathrm{N}$.

The set of whole numbers greater than $50$ is an infinite set.

If $\mathrm{A}$ and $\mathrm{B}$ are two different infinite sets, then $\mathrm{n}( \mathrm{A})=\mathrm{n}( \mathrm{B})$.
