Question : If $x=a\sec\theta$ and $y=b\tan\theta$, then $\frac{x^{2}}{a^{2}}-\frac{y^{2}}{b^{2}}=?$
Option 1: 1
Option 2: 2
Option 3: 3
Option 4: 4
Correct Answer: 1
Solution : Given: $x=a\sec\theta$ and $y=b\tan\theta$ ⇒ $\frac{x^{2}}{a^{2}}=\frac{a^{2}\sec^{2}\theta}{a^{2}}=\sec^{2}\theta$ ⇒ $\frac{y^{2}}{b^{2}}=\frac{b^{2}\tan^{2}\theta}{b^{2}}=\tan^{2}\theta$ The value of $\frac{x^{2}}{a^{2}}-\frac{y^{2}}{b^{2}}=\sec^{2}\theta-\tan^{2}\theta=1$ Hence, the correct answer is 1.
Question : How many non-major (minor) ports are there in India?
Option 1: 168
Option 2: 154
Option 3: 246
Option 4: 200
Correct Answer: 200
Solution : The correct answer is 200.
India has approximately 200 non-major (minor) ports, contributing significantly to the country's maritime trade alongside its 13 major ports. These minor ports handle both coastal and fishing trade, playing a crucial role in regional economies and national development. The

Question : The angle of elevation of the top of a building at a distance of 70 m from its foot on a horizontal plane is found to be 60°. Find the height of the building.
Option 1: $70 \sqrt{3} \mathrm{~m}$
Option 2: $60 \sqrt{3} \mathrm{~m}$
Option 3: $50 \sqrt{3} \mathrm{~m}$
Option 4: $70 \sqrt{2} \mathrm{~m}$
Correct Answer: $70 \sqrt{3} \mathrm{~m}$
Solution : Height = AC We know, $\tan \theta=\frac{\text{Perpendicular}}{\text{Base}}$ ⇒ $\tan60° =\frac{AC}{70}$ ⇒ $\sqrt3=\frac{AC}{70}$ ⇒ $AC=70\sqrt3\text{ m}$ Hence, the correct answer is $70\sqrt3\text{ m}$.

Question : The base of a prism is a right-angle triangle whose sides are 9 cm, 12 cm, and 15 cm. Volume of this prism is 648 cm3. What will be the height of the prism?
Option 1: 14 cm
Option 2: 12 cm
Option 3: 9 cm
Option 4: 16 cm
Correct Answer: 12 cm
Solution : Given: The base of a prism is a right-angle triangle whose sides are 9 cm, 12 cm, and 15 cm. The volume of this prism is 648 cm3. Base area = $\frac{1}{2}$ × Perpendicular × Base = $\frac{1}{2}$ × 9 × 12
Question : In $t$ years, the simple interest earned on a certain amount at the rate of 10% per annum is $\frac{5}{8}$th of the principal amount. If the rate of interest is made three-fourths of 10% and the simple interest remains the same, which of the following statements is true about the changed value of time?
Option 1: It remains the same as $t$.
Option 2: It becomes three-fourths of the time $t$.
Option 3: It increases to $8 \frac{1}{3}$ years.
Option 4: It decreases to $5 \frac{1}{2}$ years.
Correct Answer: It increases to $8 \frac{1}{3}$ years.
Solution : Let the principal amount be $P$. Simple interest after $t$ years at the rate of 10% per annum = $\frac{5}{8}P$ ⇒ $\frac{P(10)t}{100}=\frac{5}{8}P$---(1) ⇒ $t=\frac{25}{4}$ years New rate of interest $=\frac{3}{4}\times 10 = 7.5\%$ Let the new time taken for $P$
