Question : Directions: Which of the following numbers will replace the question mark (?) in the given series? 5, 20, 60, 240, 720, ?
Option 1: 2580
Option 2: 2880
Option 3: 2160
Option 4: 2675
Correct Answer: 2880
Solution : Given: 5, 20, 60, 240, 720, ?
To get the required missing number in the series, multiply the number by 4 and 3 alternatively – 5 × 4 = 20; 20 × 3 = 60; 60 × 4 = 240; 240 × 3 = 720;
Question : If $\triangle A B C$ is right angled at $B, A B=12 \mathrm{~cm}$ and $\angle C A B=60^{\circ}$, determine the length of $BC$.
Option 1: $24 \sqrt{3} \mathrm{~cm}$
Option 2: $12 \mathrm{~cm}$
Option 3: $12 \sqrt{2} \mathrm{~cm}$
Option 4: $12 \sqrt{3} \mathrm{~cm}$
Correct Answer: $12 \sqrt{3} \mathrm{~cm}$
Solution : Given, $\triangle$ABC is right angled at B, where AB = 12 cm and $\angle$CAB = 60° By using the trigonometric ratio involving AB and BC. To $\angle$CAB, AB is the adjacent side and BC is the opposite side. $\tan\angle CAB$ = $\tan 60°$
Question : If $x^{4}+\frac{1}{x^{4}}=34$, what is the value of $x^{3}-\frac{1}{x^{3}} $?
Option 1: 0
Option 2: 6
Option 3: 8
Option 4: 14
Correct Answer: 14
Solution : Given: $x^{4}+\frac{1}{x^{4}}=34$ Adding 2 to both sides, we get, $⇒x^{4}+\frac{1}{x^{4}}+2=34+2$ $⇒(x^{2}+\frac{1}{x^{2}})^{2}=(6)^{2}$ $⇒x^{2}+\frac{1}{x^{2}}=6$ Subtracting 2 from both sides, we get, $⇒x^{2}+\frac{1}{x^{2}}-2=6-2$ $⇒(x-\frac{1}{x})^{2}=(2)^{2}$ $⇒x-\frac{1}{x}=2$ Now, $(x-\frac{1}{x})^3=x^3-\frac{1}{x^3}-3×x×\frac{1}{x}(x-\frac{1}{x})$ $⇒2^3=x^3-\frac{1}{x^3}-3×2$ $\therefore x^{3}-\frac{1}{x^{3}}=14$ Hence, the correct answer is 14.
Question : When did Heinrich Hertz discover the photoelectric effect and observe that shining ultraviolet light on the electrodes caused a change in voltage between them?
Option 1: 1916
Option 2: 1902
Option 3: 1990
Option 4: 1887
Correct Answer: 1887
Solution : The correct option is 1887.
In the year 1887, German physicist Heinrich Hertz made a pivotal discovery related to the photoelectric effect while researching radio waves. In the course of his experiments, Hertz utilised a spark gap consisting of two closely spaced, sharp electrodes capable
Question : If $\operatorname{cosec}\theta-\sin\theta=l$ and $\sec\theta-\cos\theta=m$, then the value of $l^2m^2(l^2+m^2+3)$ is:
Option 1: $–1$
Option 2: $0$
Option 3: $1$
Option 4: $2$
Correct Answer: $1$
Solution : Given: $\operatorname{cosec}\theta-\sin\theta=l$ and $\sec\theta-\cos\theta=m$, $l^2m^2(l^2+m^2+3)$ $=(\operatorname{cosec}\theta-\sin\theta)^2(\sec\theta-\cos\theta)^2[(\operatorname{cosec}\theta-\sin\theta)^2+(\sec\theta-\cos\theta)^2+3]$ $= (\frac{1}{\sin\theta}-\sin\theta)^2(\frac{1}{\cos\theta}-\cos\theta)^2[(\frac{1}{\sin\theta}-\sin\theta)^2+(\frac{1}{\cos\theta}-\cos\theta)^2+3]$ $=(\frac{1-\sin^2\theta}{\sin\theta})^2(\frac{1-\cos^2\theta}{\cos\theta})^2[(\frac{1-\sin^2\theta}{\sin\theta})^2+(\frac{1-\cos^2\theta}{\cos\theta})^2+3]$ $=(\frac{cos^2\theta}{\sin\theta})^2(\frac{\sin^2\theta}{\cos\theta})^2[(\frac{\cos^2\theta}{\sin\theta})^2+(\frac{\sin^2\theta}{\cos\theta})^2+3]$ $=(\frac{\cos^4\theta}{\sin^2\theta})(\frac{\sin^4\theta}{\cos^2\theta})[(\frac{\cos^4\theta}{\sin^2\theta})+(\frac{\sin^4\theta}{\cos^2\theta})+3]$ $= \sin^2\theta \cos^2\theta[\frac{\cos^6\theta+\sin^6\theta+3\sin^2\theta \cos^2\theta}{\sin^2\theta \cos^2\theta}]$ $= \cos^6\theta+\sin^6\theta+3\sin^2\theta \cos^2\theta$ $=(\cos^2\theta)^3+\sin^2\theta)^3+3\sin^2\theta \cos^2\theta$ $=(\cos^2\theta+\sin^2\theta)^3-3\cos^2\theta \sin^2\theta(\cos^2\theta+\sin^2\theta)+3\sin^2\theta \cos^2\theta$ $=1^3-3\cos^2\theta \sin^2\theta(1)+3\sin^2\theta \cos^2\theta$ $=1$ Hence, the correct answer is $1$.
