Question : The sum of the length, breadth, and height of a cuboid box is 20 cm and the total surface area of a cuboid is 256 sq. cm. What is the maximum length (in approximate) of a stick that can be placed inside the cuboid box?
Option 1: 16 cm
Option 2: 24 cm
Option 3: 32 cm
Option 4: 12 cm
Correct Answer: 12 cm
Solution : The sum of the length, breadth, and height of a cuboid box is 20 cm. ⇒ $l + b + h = 20$, Where $l$ = length, $b$ = breadth, $h$ = height The total surface area of the cuboid = 256 sq. cm.

Question : Using $\cos (A+B)=\cos A \cos B-\sin A \sin B$, find the value of $\cos 75^\circ$.
Option 1: $\frac{\sqrt{5}-1}{4}$
Option 2: $\frac{\sqrt{5}+1}{4}$
Option 3: $\frac{\sqrt{6}-\sqrt{2}}{4}$
Option 4: $\frac{\sqrt{6}+\sqrt{2}}{4}$
Correct Answer: $\frac{\sqrt{6}-\sqrt{2}}{4}$
Solution : Given: $\cos (A+B)=\cos A \cos B-\sin A \sin B$ Let $A=45^\circ, B=30^\circ$ So, $\cos (45^\circ+30^\circ) = \cos 45^\circ \cos30^\circ - \sin45^\circ \sin 30^\circ$ ⇒ $\cos 75^\circ= \frac{1}{\sqrt{2}}×\frac{\sqrt{3}}{2}-\frac{1}{\sqrt{2}}×\frac{1}{2}=\frac{\sqrt{3}-1}{2\sqrt{2}}=\frac{\sqrt{6}-\sqrt{2}}{4}$ So, the value of $\cos 75^\circ$ is $\frac{\sqrt{6}-\sqrt{2}}{4}$. Hence, the correct answer is $\frac{\sqrt{6}-\sqrt{2}}{4}$.
Question : Directions: Select the related letter cluster from the given alternatives. PZQW : NXOU :: FISK : ?
Option 1: EFPJ
Option 2: FERI
Option 3: DGQI
Option 4: HKVM
Correct Answer: DGQI
Solution : Given: PZQW : NXOU :: FISK : ?
