Correct Answer: 100 N

Solution :

The correct option is 100N.

Weight (W) = Mass (M) × acceleration due to gravity (g)

The gravitational acceleration on the surface of the moon is 1/6th of that on Earth.

Acceleration due to gravity on Earth ≈ 10m/s²

So the acceleration due

Correct Answer: $\frac{4}{3}$

Solution : Given: $x=\frac{\sqrt{5}+1}{\sqrt{5}-1}$ and $y=\frac{\sqrt{5}-1}{\sqrt{5}+1}$, then
$x^2=\frac{5+1+2\sqrt{5}}{5+1-2\sqrt{5}}$ and $y^2=\frac{5+1-2\sqrt{5}}{5+1+2\sqrt{5}}$
⇒ $x^2=\frac{6+2\sqrt{5}}{6-2\sqrt{5}}$ and $y^2=\frac{6-2\sqrt{5}}{6+2\sqrt{5}}$
and, $xy = \frac{\sqrt{5}+1}{\sqrt{5}-1}×\frac{\sqrt{5}-1}{\sqrt{5}+1}=1$
Putting the values, we get:
$\frac{x^{2}+xy+y^{2}}{x^{2}-xy+y^{2}}$
= $\frac{\frac{6+2\sqrt{5}}{6-2\sqrt{5}}+1+\frac{6-2\sqrt{5}}{6+2\sqrt{5}}}{\frac{6+2\sqrt{5}}{6-2\sqrt{5}}-1+\frac{6-2\sqrt{5}}{6+2\sqrt{5}}}$
= $\frac{\frac{(6+2\sqrt{5})^2+6^2-(2\sqrt5)^2+(6-2\sqrt{5})^2}{(6)^2-(2\sqrt{5})^2}}{\frac{(6+2\sqrt{5})^2-6^2+(2\sqrt5)^2+(6-2\sqrt{5})^2}{(6)^2-(2\sqrt{5})^2}}$
= $\frac{36+20+24\sqrt5+36-20+36+20-24\sqrt5}{36+20+24\sqrt5-36+20+36+20-24\sqrt5}$
= $\frac{128}{96}$ = $\frac{4}{3}$
Hence, the correct answer is $\frac{4}{3}$.

Correct Answer: 515

Solution : Given:
206, 309, 412, ?, 618, 721

In the given series, add 103 to the previous number to obtain the next number.
206 + 103 = 309; 309 + 103 = 412; 412 + 103 = 515; 515 + 103 = 618; 618 + 103
