Directions: In the following questions, the Assertions (A) and Reason(s) (R) have been put forward. Read both the statements carefully and choose the correct alternative from the following:
Assertion (A): Assertion (A):For an objective function Z= 15x + 20y, corner points are (0, 0), (10, 0), (0, 15) and (5, 5). Then optimal values are 300 and 0 respectively.
Reason (R): The maximum or minimum value of an objective function is known as optimal value of LPP. These values are obtained at corner points.

If $f(x)=|\cos x|$, then $f\left(\frac{3 \pi}{4}\right)$ is

If $y = {\sin ^{ - 1}}(x\sqrt {1 - x} + \sqrt x \sqrt {1 - {x^2})} , $ then ${{dy} \over {dx}} = $

The Convex Polygon Theorem states that the optimum $($maximum or minimum$)$ solution of a $\text{LPP}$ is attained at atleastone of the $........$ of the convex set over which the solution is feasible.

At $\text{x}=\frac{5\pi}{6}, $ $\text{f}(\text{x})=2\sin3\text{x}+3 \cos3\text{x}$ is:

If $f(x) = x + tanx$ and $g(x)$ is inverse of $f(x)$ then $g'(x)$ is equal to

If a line makes 45°, 60° with positive direction of axes x and y then the angles it makes with the z-axis is:

A computer producing factory has only two plants $T_1$ and $T_2$. Plant $T_1$ produces $20 \%$ and plant $T_2$ produces $80 \%$ of the total computers produced. $7 \%$ of computers produced in the factory turn out to be defective. It is known that

$P$ (computer turns out to be defective given that it is produced in plant $T_1$ )

$=10 P\left(\right.$ computer turns out to be defective given that it is produced in plant $\left.T_2\right)$,

where $P(E)$ denotes the probability of an event $E$. A computer produced in the factory is randomly selected and it does not turn out to be defective. Then the probability that it is produced in plant $T_2$ is

If $d$ is the determinant of a square matrix $A$ of order $n,$ then the determinant of its adjoint is :

If $y =\frac{x}{{a\, +\frac{x}{{b\, +\frac{x}{{a\, + \frac{x}{{b\, +\frac{x}{{a\, + \frac{x}{{b\, }}......+\infty }}\,\,\,}}\,\,\,}}\,\,\, }}\,\,\, }}\,\,\,$ then $\frac{{dy}}{{dx}}$=
