Correct Answer: $2\operatorname{cosec}A$

Solution : Given: $\frac{\sin A}{1+ \cos A}+\frac{\sin A}{1- \cos A}$
= $\frac{\sin A(1–\cos A)+\sin A (1+\cos A)}{(1+ \cos A)(1- \cos A)}$
= $\frac{\sin A–\sin A \cos A+\sin A+\sin A \cos A}{(1- \cos^{2} A)}$
= $\frac{2\sin A}{\sin^{2}A}$
= $\frac{2}{\sin A}$
= $2 \operatorname{cosec}A$
Hence, the correct answer is

Correct Answer: $\frac{48}{7}$

Solution : Let the four numbers be $p, q, r$ and $s$.
$⇒\frac{p+q+ r+s}{4}=12$
$⇒p+q+r+s=48$ ...(i)
$⇒\frac{p+q+r}{3}=2s$
$⇒p+q+r=6s$ ...(ii)
Putting equation (ii) in equation (i), we get,
$⇒6s+s=48$
$⇒7s=48$
$\therefore s=\frac{48}{7}$
Hence, the correct answer is $\frac{48}{7}$.

Correct Answer: 1

Solution : Taking dice positions 1 and 2 with 2 as common face,

Moving clockwise from the common face with 2,

 Pairs of opposite faces –

So, the opposite face to the face containing 2 is 1. Hence, the first option is correct.

Correct Answer: 125.44

Solution :

Given that the radius of the circle = $14\sqrt{2}$ cm
The diameter of the circle = $2 \times 14\sqrt{2} = 28\sqrt{2}$ cm.
The side of the larger square (PQRS) = $\frac{\operatorname{diameter}}{\sqrt2}=28$ cm.
TO = half the side of the larger square = $14$ cm.
The
