Question : What is the value of $64x^{3} + 36x^{2}y + 24xy^{2} + 2y^{3}$, when $x = 3$ and $y = -4?$
Option 1: $304$
Option 2: $1456$
Option 3: $1584$
Option 4: $432$
Correct Answer: $1456$
Solution : Given: $x = 3, y = -4$ So, the value of $64x^{3} + 36x^{2}y + 24xy^{2} + 2y^{3}$ $=x^{2}(64x + 36y) + y^{2}(24x + 2y)$ $=3^{2}[(64 × 3) + (36 × -4)] + (-4)^{2}[(24 × 3) + (2 × -4)]$ $=9 × [192 -144] +
Question : If $\left(\frac{\cos A}{1-\sin A}\right)+\left(\frac{\cos A}{1+\sin A}\right)=4$, then what will be the value of $A$? $\left(0^{\circ}<\theta<90^{\circ}\right)$
Option 1: $90^{\circ}$
Option 2: $45^{\circ}$
Option 3: $60^{\circ}$
Option 4: $30^{\circ}$
Correct Answer: $60^{\circ}$
Solution : Given: $\left(\frac{\cos A}{1-\sin A}\right)+\left(\frac{\cos A}{1+\sin A}\right) = 4$ ⇒ $\frac{\cos A(1+\sin A) + \cos A(1-\sin A)}{(1-\sin A)(1+\sin A)} = 4$ ⇒ $\cos A + \cos A \sin A + \cos A - \cos A \sin A = 4(1-\sin^2A)$ ⇒ $2\cos A = 4 \cos^2 A$

Question : If $\small a^{3}+3a^{2}+9a=1$, then what is the value of $a^{3}+\frac{3}{a}$?
Option 1: 31
Option 2: 26
Option 3: 28
Option 4: 24
Correct Answer: 28
Solution : $a^{3}+3a^{2}+9a=1$ .......(i) Multiply the equation by $\frac{3}{a}$ both sides, ⇒ $3a^{2}+9a+27=\frac{3}{a}$ ......(ii) Subtracting (ii) from (i), ⇒ $a^{3}-27=1-\frac{3}{a}$ $\therefore a^{3}+\frac{3}{a}=28$ Hence, the correct answer is 28.
