Correct Answer: 136

Solution : Given:
+ means ÷, ÷ means × and × means +
64 + 8 × 32 ÷ 4 = ?

On replacing the signs in the equation according to the instructions given, we get –
= 64 ÷ 8 + 32 × 4
= 8

Correct Answer: $3 \text{PQ}^2=4 \text{PM}^2$

Solution :
In an equilateral triangle $\text{PQR}$, all three sides are equal, so let's denote the length of each side as $a$.
Given: $\text{PM}\perp \text{QR}$
$\therefore$ $PQ^2 = PM^2 + MQ^2$ [By Pythagoras theorem]
$\text{MQ}$ is half of $\text{QR}$ (as it bisects $\text{QR}$ when $\text{PM}$

Correct Answer: $2 \sec A$

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