Question : The expression $\frac{\tan ^6 \theta-\sec ^6 \theta+3 \sec ^2 \theta \tan ^2 \theta}{\tan ^2 \theta+\cot ^2 \theta+2}, 0^{\circ}<\theta<90^{\circ}$, is equal to:
Option 1: $\sec ^2 \theta \operatorname{cosec}^2 \theta$
Option 2: $-\sec ^2 \theta \operatorname{cosec}^2 \theta$
Option 3: $\cos ^2 \theta \sin ^2 \theta$
Option 4: $-\cos ^2 \theta \sin ^2 \theta$
Correct Answer: $-\cos ^2 \theta \sin ^2 \theta$
Solution : $\frac{\tan ^6 \theta-\sec ^6 \theta+3 \sec ^2 \theta \tan ^2 \theta}{\tan ^2 \theta+\cot ^2 \theta+2}$ Since $0^{\circ}<\theta<90^{\circ}$, putting $\theta=45^{\circ}$ $\frac{\tan ^6 45^{\circ}-\sec ^6 45^{\circ}+3 \sec ^2 45^{\circ} \tan ^2 45^{\circ}}{\tan ^2 45^{\circ}+\cot ^245^{\circ}+2}$ $=\frac{1-(\sqrt2)^6+ 3\times (\sqrt2)^2\times 1}{1+1+2}$ $=\frac{1-8+6}{1+1+2}=-\frac{1}{4}$ From option
Question : Directions: How many triangles are there in the given figure?
Option 1: 14
Option 2: 15
Option 3: 16
Option 4: 19
Correct Answer: 15
Solution : The figure can be labeled as shown below –
There are a total of 15 triangles in the figure. They are AHB, AHD, BHC, DHC, ABD, BCD, BAC, ADC, EHC, CHF, GHF, CHG, BHE, DHG, DHF.
Hence, the second option is correct.
Question : Simplify the given expression. $ \frac{432 \times 432+247 \times 247-432 \times 247}{432 \times 432 \times 432+247 \times 247 \times 247} $
Option 1: $\frac{1}{259}$
Option 2: $\frac{1}{185}$
Option 3: $\frac{1}{679}$
Option 4: $\frac{1}{450}$
Correct Answer: $\frac{1}{679}$
Solution : $\frac{432^2+247^2-432 \times 247}{432^3+247^3}$ Using identity $x^3+y^3 = (x+y)(x^2+y^2-x \times y)$, $\frac{432^2+247^2-432 \times 247}{(432+247)(432^2+247^2-432 \times 247)}$ $=\frac{1}{(432+247)}$ $= \frac{1}{679}$ Hence, the correct answer is $\frac{1}{679}$.
Question : Comprehension: In the following passage, some words have been deleted. Read the passage carefully and select the most appropriate option to fill in each blank. India is one of the largest producers of tea in the world. The industry is (1)________ recognised as technically very well (2) ________. The Indian tea industry is a (3) ________one traditionally. Tea has been used in India for (4) ________ purposes as well as for (5) ________. Question Select the most appropriate option to fill in the blank number 2.
Option 1: complex
Option 2: establish
Option 3: pampered
Option 4: equipped
Correct Answer: equipped
Solution : The most appropriate option to fill in the blank is the fourth option.
Explanation: The word technically in the sentence indicates that the industry is being described in terms of technical aspects. The adjective equipped fits well in this context, suggesting that the Indian tea
Question : Directions: In the following question, some parts of the sentence have errors, and some are correct. Find out which part of the sentence has an error. The number of that part is the answer. If a sentence is error-free, your answer is "No Error".
Could she cite (1) / any precedent in support (2) / for her case? (3) / No Error (4)
Option 1: 1
Option 2: 2
Option 3: 3
Option 4: 4
Correct Answer: 3
Solution : The error lies in the third part of the sentence.
Explanation: The preposition "for" is incorrect in this context. When talking about supporting something, the correct preposition to use is "of". The term "in support of" means strengthening something.
Hence, the correct sentence should be:
Question : Direction: In each of the following question, which one set of letters when sequentially placed at the gaps in the given letter series shall complete it?
SH _ ELAS _ EELA _ HEELASHEE _ A
Option 1: HHSS
Option 2: EEHS
Option 3: EHSL
Option 4: ELHA
Correct Answer: EHSL
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, SH _ / ELA / S _ E/ ELA / _ HE
Question : If $y+\frac{1}{y}=11$, then the value of $y^3-\frac{1}{y^3}$ is:
Option 1: $345 \sqrt{13}$
Option 2: $360 \sqrt{13}$
Option 3: $352 \sqrt{13}$
Option 4: $368 \sqrt{13}$
Correct Answer: $360 \sqrt{13}$
Solution : Given, $y+\frac{1}{y}=11$ Squaring both sides, we get: $⇒(y+\frac{1}{y})^2=11^2$ $⇒(y-\frac{1}{y})^2+4(y)(\frac{1}y)=121$ $⇒(y-\frac{1}{y})^2+4=121$ $⇒(y-\frac{1}{y})^2=121-4$ $⇒(y-\frac{1}{y})=3\sqrt{17}$ Cubing both sides, we get: $⇒(y-\frac{1}{y})^3=(3\sqrt{17})^3$ $⇒y^3-\frac{1}{y^3}-3(y)(\frac{1}{y})(y-\frac{1}{y})=351\sqrt{13}$ $⇒y^3-\frac{1}{y^3}-3(3\sqrt{17})=351\sqrt{13}$ $⇒y^3-\frac{1}{y^3}=351\sqrt{13}+9\sqrt{13}$ $\therefore y^3-\frac{1}{y^3}=360\sqrt{13}$ Hence, the correct answer is $360\sqrt{13}$.
Question : Directions: In a certain code language, if PDFJARS is written as OCELZQR and MHCXBTU is written as LGBZAST, how will ZVDGENQ be written in the same code language?
Option 1: XUYCIMP

Option 3: XUCDEMQ
Option 4: XVDEDNO
Correct Answer: YUCIDMP
Solution : Given: PDFJARS is written as OCELZQR. MHCXBTU is written as LGBZAST.
Subtract 1 from the place values of the letters except the middle one; add 2 to the place value of the letter in the middle of the given word. Like, PDFJARS→P – 1 =
