Question : If $g=(2-\sqrt{3})$, what will be the value of $\left(g^3-\frac{1}{g^3}\right)$?
Option 1: $-30 \sqrt{3}$
Option 2: 52
Option 3: $30 \sqrt{3}$
Option 4: –52
Correct Answer: $-30 \sqrt{3}$
Solution : Given, $g=(2-\sqrt{3})$ ⇒, $\frac{1}{g}=\frac{1}{2-\sqrt{3}}$ ⇒ $\frac{1}{g}=\frac{2+\sqrt{3}}{(2-\sqrt{3})(2+\sqrt{3})}$ ⇒ $\frac{1}{g}=2+\sqrt{3}$ $\left(g^3-\frac{1}{g^3}\right)=(g-\frac{1}{g})(g^2+\frac{1}{g^2}+g×\frac{1}{g})$ ⇒ $\left(g^3-\frac{1}{g^3}\right)=(2-\sqrt{3}-(2+\sqrt{3}))((4+3-4\sqrt{3})+(4+3+4\sqrt{3})+1)$ ⇒ $\left(g^3-\frac{1}{g^3}\right)=-2\sqrt{3}(15)$ ⇒ $\left(g^3-\frac{1}{g^3}\right)=-30\sqrt{3}$ Hence, the correct answer is $-30\sqrt{3}$.

Question : A train travels for 2 hours at a speed of 6 m/s. What is the distance covered by the train in the mentioned duration of time?
Option 1: 40.8 km
Option 2: 36.4 km
Option 3: 46.6 km
Option 4: 43.2 km
Correct Answer: 43.2 km
Solution : Distance = Speed × Time Given: Speed = 6 m/s Time = 2 hours = 7200 seconds (since 1 hour = 3600 seconds) Substituting these values into the formula, Distance = 6 × 7200 = 43200 m = 43.2 km Hence, the correct answer
Question : In the shown figure, BC is a chord and CD is a tangent through the point C. If $\angle AOC=112^{\circ}$, then find $\angle ACD$.
Option 1: 63°
Option 2: 59°
Option 3: 65°
Option 4: 56°
Correct Answer: 56°
Solution : The angle subtended by an arc of a circle at its centre is twice the angle it subtends on any point of the circle's circumference. So, $\angle$AOC = 2 $\angle$ABC ⇒ 112°= 2 $\angle$ABC ⇒ $\angle$ABC = 56° Also, $\angle$ABC = $\angle$ACD ⇒ $\angle$ACD =
Question : Directions: Find the missing number from the given responses in the following question.
Option 1: 5052
Option 2: 5100
Option 3: 5094
Option 4: 4860
