Question : The value of $\left(2 \cos ^2 \theta-1\right)\left[\frac{1+\tan \theta}{1-\tan \theta}+\frac{1-\tan \theta}{1+\tan \theta}\right]$ is:
Option 1: $2$
Option 2: $0$
Option 3: $\frac{\sqrt{3}}{2}$
Option 4: $1$
Correct Answer: $2$
Solution : Given expression, $\left(2 \cos ^2 \theta-1\right)\left[\frac{1+\tan \theta}{1-\tan \theta}+\frac{1-\tan \theta}{1+\tan \theta}\right]$ We know, $\tan\theta=\frac{\sin\theta}{\cos\theta}$ = $(2\cos^2\theta-(\sin^2\theta+\cos^2\theta))\left[\frac{1+\frac{\sin\theta}{\cos\theta}}{1-\frac{\sin\theta}{\cos\theta}}+\frac{1-\frac{\sin\theta}{\cos\theta}}{1+\frac{\sin\theta}{\cos\theta}}\right]$ = $(2\cos^2\theta-\sin^2\theta-\cos^2\theta))\left[\frac{\cos\theta+\sin\theta}{\cos\theta-\sin\theta}+\frac{\cos\theta-\sin\theta}{\cos\theta+\sin\theta}\right]$ = $(\cos^2\theta-\sin^2\theta)\left[\frac{(\cos\theta+\sin\theta)^2+(\cos\theta-\sin\theta)^2}{(\cos\theta-\sin\theta)(\cos\theta+\sin\theta)}\right]$ = $(\cos^2\theta-\sin^2\theta)\left[\frac{\cos^2\theta+\sin^2\theta+2\sin\theta\cos\theta+\cos^2\theta+\sin^2\theta-2\sin\theta\cos\theta}{\cos^2\theta-\sin^2\theta}\right]$ = $1+1$ [As $\cos^2\theta+\sin^2\theta=1$] = $2$ Hence, the correct answer is $2$.
Question : Directions: Select the option that is related to the fifth number in the same way as the second number is related to the first number and the fourth number is related to the third number. 17 : 189 :: 13 : 69 :: 18 : ?
Option 1: 224
Option 2: 241
Option 3: 214
Option 4: 242
Correct Answer: 224
Solution : Given: 17 : 189 :: 13 : 69 :: 18 : ?
Like, 17 : 189→(172) – 100 = 289 – 100 = 189 13 : 69→(132) – 100 = 169 – 100 = 69 Similarly, for (18 : ?)→(182
Question : Select the most appropriate option to substitute the bracketed segment in the given sentence. If there is no need to substitute it, select 'no substitution required'. The unit twitched like a bird (preening it's plumage and becomes motionless).
Option 1: preening its plumage and became motionless
Option 2: No substitution required
Option 3: preening it's plumage while becoming motionless
Option 4: to preen it's plumage and becomes motionless
Correct Answer: preening its plumage and became motionless
