Correct Answer: 50

Solution : Third proportional to $a$ and $b$ is given by $\frac{b^2}{a}$, where $a$ = 8, $b$ = 20.
So, the third proportional to 8 and 20 is
= $\frac{20^2}{8}$
= $\frac{400}{8}$
= $50$
Hence, the correct answer is 50.

Correct Answer: $6 \sqrt{3}$

Solution :

O is a point in the interior of $\triangle \mathrm{ABC}$
OA = 12 cm
OC = 9 cm
$\angle A O B=\angle B O C=\angle C O A$
$\angle A B C=60^{\circ}$
$\angle A O B=\angle B O C=\angle C O A=\frac{360^{\circ}}{3} = 120^{\circ}$

Correct Answer: 20%

Solution : Given: A table is bought for Rs. 2450 and sold for Rs. 2940.
Here the cost price (CP) = Rs. 2450
The selling price (SP) = Rs. 2940
So, the gain percentage = $\frac{SP-CP}{CP}×100$
= $\frac{2940-2450}{2450}×100$
= $\frac{490}{2450}×100$
= 20%
Hence, the correct answer is

Correct Answer: 486 cm

Solution : The volume of the sphere,$V_{\text{s}} = \frac{4}{3}\pi r_{\text{s}}^3$ and the volume of the cylinder is given by the formula $V_{\text{c}} = \pi r_{\text{c}}^2 h_{\text{c}}$ where $r_{\text{s}}$ is the radius of the sphere, $r_{\text{c}}$ is the radius of the base of the cylinder, and $h_{\text{c}}$
