Correct Answer: $0$

Solution : Given: $x+\frac{1}{x}=\sqrt{3}$
Cubing both sides, we get
$x^3+\frac{1}{x^3}+3(x)(\frac{1}{x})(x+\frac{1}{x})=3\sqrt{3}$
⇒ $x^3+\frac{1}{x^3}+3\sqrt{3}=3\sqrt{3}$
⇒ $x^6+1=0$
The expression is $x^{30}+x^{24}+x^{18}+x^{12}+x^{6}+1$
$=x^{30}+x^{24}+x^{18}+x^{12}$
$=x^{30}+x^{24}+x^{12}(x^{6}+1)$
$=x^{30}+x^{24}$
$=x^{24}(x^{6}+1)$
$=0$
Hence, the correct answer is $0$.

Correct Answer: Object-Oriented Language

Solution : The correct answer is Object-Oriented Language.

High-level, general-purpose programming languages like C++ are made for creating systems and applications. It was created as an addition to the C programming language by Bjarne Stroustrup at Bell Laboratories in 1983. Procedural, functional, and generic programming

Correct Answer: 34 cm

Solution :
Given: $r_1=20$ and $r_2=4$
Let $x$ be the distance between two centres.
We know that,
Direct common tangent = $\sqrt{d^2-(r_1-r_2)^2}$, where $d$ is the distance between the centres and $r_1$ and $r_2$ are the radii of the circles.
⇒ $30=\sqrt{x^2-(20-4)^2}$
⇒ $30=\sqrt{x^2-16^2}$
⇒ $900=x^2-256$

Parsimony: It is a synonym of frugality, so it's not an antonym.

Extravagance: This is the correct antonym for frugality. Extravagance means

Correct Answer: 56

Solution : Let the two numbers as $9x$ and $16x$.
According to the problem, if both numbers are increased by 40, their ratio becomes 2 : 3.
$⇒\frac{9x + 40}{16x + 40} = \frac{2}{3}$
$⇒27x + 120 = 32x + 80$
$⇒5x = 40$
$⇒x = 8$
