Correct Answer: North

Solution : Firstly, we will draw the diagram as per the given instructions –


Here, A is the starting point and D is the endpoint.

So, Rajneesh is facing in the north direction. Hence, the first option is correct.

Correct Answer: Ribosome

Solution : The correct option is Ribosome.

Ribosomes are cellular structures responsible for protein synthesis. They can be found in both prokaryotic and eukaryotic cells. Ribosomes read the genetic code from messenger RNA (mRNA) and facilitate the assembly of amino acids into a polypeptide chain, forming

Correct Answer: 48 : 41

Solution : Total production of P-type vehicles = 100 + 125 + 200 + 225 + 275 + 275 = 1200
Total production of Q-type vehicles = 175 + 150 + 125 + 175 + 175 + 225 = 1025
Required ratio = 1200 :

Correct Answer: Hard rubber

Solution : The correct answer is Hard rubber.

Hard rubber is not a conductor of electricity. It is an insulator or non-conductor of electricity. Rubber, especially hard rubber, does not allow the flow of electric current and is used in various electrical applications to insulate

Correct Answer: $\frac{321}{323}$

Solution : $x=\frac{\sqrt{5}-\sqrt{4}}{\sqrt{5}+\sqrt{4}} = \frac{(\sqrt{5}-\sqrt{4})^2}{(\sqrt{5}+\sqrt{4})(\sqrt{5}-\sqrt{4})} = \frac{5+4-4\sqrt5}{5-4} = 9-4\sqrt5$
$y=\frac{\sqrt{5}+\sqrt{4}}{\sqrt{5}-\sqrt{4}} = \frac{(\sqrt{5}+\sqrt{4})^2}{(\sqrt{5}-\sqrt{4})(\sqrt{5}+\sqrt{4})} = \frac{5+4+4\sqrt5}{5-4} = 9+4\sqrt5$
⇒ $xy=\frac{\sqrt{5}-\sqrt{4}}{\sqrt{5}+\sqrt{4}}×\frac{\sqrt{5}+\sqrt{4}}{\sqrt{5}-\sqrt{4}}=1$
and $x+y=9-4\sqrt5+9+4\sqrt5=18$
Now, $\frac{x^2-x y+y^2}{x^2+x y+y^2}$
= $\frac{x^2+2xy+y^2-3xy}{x^2+2xy+y^2-xy}$
= $\frac{(x+y)^2-3xy}{(x+y)^2-xy}$
= $\frac{(18)^2-3}{(18)^2-1}$
= $\frac{321}{323}$
Hence, the correct answer is $\frac{321}{323}$.

Correct Answer: 47 kg

Solution : Given: There are 15 students in a class. Their average weight is 40 kg.
Before one student left, the combined weight of the class was: 15 × 40 = 600 kg
After one student left the class, the remaining student's combined weight = 14
