Correct Answer: $\frac{5+\sqrt{3}}{2 \sqrt{3}}$

Solution : Given: $\sin 30^{\circ}+\cos 30^{\circ}+\tan 30^{\circ}$
Putting the values, we get:
$=\frac{1}{2}+\frac{\sqrt3}{2}+\frac{1}{\sqrt3}$
$=\frac{\sqrt3+3+2}{2\sqrt3}$
$=\frac{5+\sqrt3}{2\sqrt3}$
Hence, the correct answer is $\frac{5+\sqrt3}{2\sqrt3}$.

Solution : As per the given graph:
In 2017, the sales of each brand increased by the same percentage as it did in the year 2016.
The increase in sales of Brand 1 in 2016 = $\frac{7.5-5.5}{5.5}×100=36.36\%$
The sales of Brand 1 in 2017 = $7.5+(7.5×\frac{36.36}{100})=10.2$ units

Correct Answer: 57

Solution : Given:
66 A 3 D 11 B 43 C 48 D 12 = ?

After replacing the letters with the mathematical signs, we get –
= 66 × 3 ÷ 11 + 43 – 48 ÷ 12
= 18 + 43 – 4
= 61

Correct Answer: 1

Solution : Given expression,
$x^4+x^{-4}=47$
⇒ $x^4+\frac{1}{x^4}=47$
Adding 2 on both sides,
⇒ $x^4+\frac{1}{x^4}+2=47+2$
⇒ $x^4+\frac{1}{x^4}+2\times x^2\times\frac{1}{x^2}=49$
⇒ $(x^2+\frac{1}{x^2})^2=7^2$ [As $a^2+b^2+2ab=(a+b)^2$]
⇒ $x^2+\frac{1}{x^2}=7$
Again adding 2 on both sides,
⇒ $x^2+\frac{1}{x^2}+2=7+2$
⇒ $x^2+\frac{1}{x^2}+2\times x\times\frac1x=9$
⇒ $(x+\frac1x)^2=3^2$
⇒ $x+\frac1x=3$
⇒ $x+\frac1x-2=3-2$
$\therefore x+\frac1x-2=1$
Hence, the correct answer is
