Solution : Given:
We have to check the order of the letters in the given series.
To fill the series we have to divide the series, BR _ _ / NB _ O / _ NB.
So, the series
Question : If $\tan x = –\frac{12}{5}$, where $x$ lies in the second quadrant, what is the value of $\sin x-\cot x$?
Option 1: $\frac{209}{156}$
Option 2: $\frac{169}{156}$
Option 3: $\frac{156}{209}$
Option 4: $\frac{144}{169}$
Correct Answer: $\frac{209}{156}$
Solution : In the second quadrant, $\sin x$ and $\operatorname{cosec x}$ are positive. $\tan x = –\frac{12}{5}$ $⇒\cot x=\frac{1}{\tan x}=-\frac{5}{12}$ We know, $\sec^2x -\tan^2x=1$ $⇒\sec^2x=1+(–\frac{12}{5})^2$ $⇒\sec^2x=1+\frac{144}{25}$ $⇒\sec^2x=\frac{169}{25}$ $⇒ \sec x=\frac{13}{5}$ $⇒\cos x = \frac{5}{13}$ $\therefore\sin x = \sqrt{1-\cos^2x}=\sqrt{1-\frac{25}{169}}=\frac{144}{169}=\frac{12}{13}$ $\sin x - \cot x = \frac{12}{13} – (-\frac{5}{12})
Question : Select the most appropriate synonym of the given word.
Authentic
Option 1: Genuine
Option 2: False
Option 3: Doubtful
Option 4: Corrupt

Question : Directions: Select the odd group of numbers. (NOTE: Operations should be performed on the whole numbers, without breaking down the numbers into their constituent digits. E.g.13 – operations on 13 such as adding /subtracting /multiplying etc. to 13 can be performed. Breaking down 13 into 1 and 3 and then performing mathematical operations on 1 and 3 is not allowed)
Option 1: (57 – 53 – 49)
Option 2: (60 – 56 – 52)
Option 3: (50 – 46 – 42)
Option 4: (47 – 43 – 37)
Correct Answer: (47 – 43 – 37)
Solution : Let's check each option – First option: (57 – 53 – 49); 57 – 4 = 53 and 53 – 4 = 49 Second option: (60 – 56 – 52); 60 – 4 = 56 and 56 – 4 = 52
Question : $A_1$ and $A_2$ are two regular polygons. The sum of all the interior angles of $A_1$ is $1080^{\circ}$. Each interior angle of $A_2$ exceeds its exterior angle by $132^{\circ}$. The sum of the number of sides $A_1$ and $A_2$ is:
Option 1: 21
Option 2: 22
Option 3: 23
Option 4: 24
Correct Answer: 23
Solution : Let the sides of polygon $A_1$ be $n$. The sum of all the interior angles $A_1 = 1080^{\circ}$ $\Rightarrow (n-2)\times 180^{\circ} = 1080^{\circ}$ $\Rightarrow (n-2) =6$ $\Rightarrow n=8$ Now, Let $I$ be the interior angle and $E$ be the exterior angle. $\Rightarrow I-E = 132^{\circ}$.....(1)
Question : Study the following table and answer the question that follows.
Total number of students enrolled
What is the average number of students who opted for other than statistics subjects in schools A and D?
Option 1: 7340
Option 2: 360
Option 3: 355
Option 4: 350
Correct Answer: 350
Solution : In school A, Number of students opted for other than statistics subject = (100 - 20)% of 450 = $\frac{80}{100}\times 450$ = 360 In school D, Number of students opted for other than statistics subject = (100 - 15)% of 400 = $\frac{85}{100}\times 400$ =
