Question : If $p^2+\frac{1}{p^2}=14$, then find the value of $\left(p^3+\frac{1}{p^3}\right)$.
Option 1: 56
Option 2: 60
Option 3: 48
Option 4: 52
Correct Answer: 52
Solution : Given: $p^2+\frac{1}{p^2}=14$ we know that, $p^2+\frac{1}{p^2}=(p+\frac{1}{p})^2-2\times p\times \frac{1}{p}$ $⇒(p+\frac{1}{p})^2-2\times p\times \frac{1}{p}=14$ $⇒(p+\frac{1}{p})^2=14+2$ $⇒(p+\frac{1}{p})^2=16$ $⇒(p+\frac{1}{p})=4$ Now cubing both sides, we get: $⇒(p+\frac{1}{p})^3=4^3$ $⇒p^3+\frac{1}{p^3}+3\times p\times \frac{1}{p}(p+ \frac{1}{p})=4^3$ $⇒p^3+\frac{1}{p^3}+3\times4=64$ $⇒p^3+\frac{1}{p^3}=64-12$ $⇒p^3+\frac{1}{p^3}=52$ Hence, the correct answer is 52.

Option 3: 1321
Option 4: 1728

Solution : Let's check the options – First option: 125→(5)3 = 125 Second option: 512→(8)3 = 512 Third option: 1321→1321 is not a cube of any number. Fourth option: 1728→(12)3 = 1728
So, the third option does not follow a similar pattern as the
Question : If A = 60°, B = 30°, then find the value of sin A cos B + cos A sin B.
Option 1: 0
Option 2: 12
Option 3: 13
Option 4: 1
Correct Answer: 1
Solution : Given that A = 60°, B = 30° sin A cos B + cos A sin B = sin (A + B) = sin (60° + 30°) = sin 90° = 1 Hence, the correct answer is 1.
