If A+B=\(\begin{pmatrix} 2&-4 \\4&0 \end{pmatrix}\) and 3B=\(\begin{pmatrix} -9&6 \\3&12 \end{pmatrix}\) then A+4B is
- \(\begin{pmatrix} -7&2 \\1&12 \end{pmatrix}\)
- \(\begin{pmatrix} 11&10 \\7&12 \end{pmatrix}\)
- \(\begin{pmatrix} -11&-10 \\7&12 \end{pmatrix}\)
- \(\begin{pmatrix} -7&2 \\7&12 \end{pmatrix}\)
The Correct Option is D

- If \(P = \{3m : m \in \mathbb{N}\}\) and \(Q = \{3m : m \in \mathbb{N}\}\) are two sets, then
- If the set \(\left( Re \left( \frac{z-\bar{z}+z\bar{z}}{2-3z+5\bar{z}}\right) : z ∈ C, Re(z)=3 \right)\) is equal to the interval (α,β), then 24(β-α) is equal to
Let $P(S)$ denote the power set of $S=\{1,2,3, \ldots , 10\}$. Define the relations $R_1$ and $R_2$ on $P(S)$ as $A_1 B$ if $\left(A \cap B^c\right) \cup\left(B \cap A^c\right)=\emptyset$ and $A_2 B$ if $A \cup B^c=B \cup A^c, \forall A, B \in P(S)$. Then :
