Option 1: 12
Option 2: 14
Option 3: 16
Option 4: 10
Correct Answer: 12
Solution : Given: 4, 6, 6, 10, 8, 14, 10, 18, ?, 22

Question : The radius of a circle is increased by 10%. The percentage increase in its area is:
Option 1: 10%
Option 2: 11%
Option 3: 20%
Option 4: 21%
Correct Answer: 21%
Solution : Given: The radius of a circle is increased by 10%. Let the radius be r units, then area = $\pi r^2$ sq. units After a 10% increase, new radius = $(r+r×\frac{10}{100})=\frac{11r}{10}$ units Now, the area = $\pi (\frac{11r}{10})^2=\frac{121\pi r^2}{100}$ sq. units Therefore, the percentage increase
Question : If $x-\frac{1}{x}=2$, then what is the value of $x^2+\frac{1}{x^2}$?
Option 1: 4
Option 2: 5
Option 3: 3
Option 4: 6
Correct Answer: 6
Solution : Given: $x-\frac{1}{x}=2$ We know that the algebraic identity is $(x-\frac{1}{x})^2=x^2+\frac{1}{x^2}-2$ $x-\frac{1}{x}=2$ On squaring both sides of the above equation, we get, ⇒ $(x-\frac{1}{x})^2=2^2$ ⇒ $x^2+\frac{1}{x^2}-2=4$ ⇒ $x^2+\frac{1}{x^2}=4+2$ ⇒ $x^2+\frac{1}{x^2}=6$ Hence, the correct answer is 6.
Question : If $\frac{x}{8}+\frac{8}{x}=1$, then the value of $x^3$ is:
Option 1: – 256
Option 2: – 512
Option 3: 256
Option 4: 512
Correct Answer: – 512
Solution : Given, $\frac{x}{8}+\frac{8}{x}=1$ ⇒ $x^2+64=8x$ ⇒ $x^2-8x+64=0$ ⇒ $(x+8)(x^2-8x+64)=0$ ⇒ $(x^3+8^3)=0$ ⇒ $x^3=-512$ Hence, the correct answer is – 512.
