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 : The sentences of a paragraph are given below in jumbled order. Arrange the sentences in the correct order to form a meaningful and coherent paragraph.
A) Human relationships are a matter of great concern for every one of us B) Nevertheless, social scientists have attached many other elements that actually help us for a good social life C) As it helps us all to have a coordinated, balanced, and approachable life D) The present generation fails to take cognisance of all such elements and fall prey to a lonely life, risking happiness.
Option 1: ADBC
Option 2: DABC
Option 3: ABCD
Option 4: ACBD
Correct Answer: ACBD
Solution : The correct choice is the fourth option.

Question : Directions: Given below are two statements and two conclusions. Take the statements to be true even if they are at variance with commonly known facts, and decide whether the conclusion(s) follow(s) the given statements. Statements: All irons are coppers. All coppers are aluminiums. Conclusions: I. Some aluminum are irons. II. Some aluminum are coppers.
Option 1: Only conclusion II follows
Option 2: Neither conclusion I nor II follows
Option 3: Only conclusion I follows
Option 4: Both conclusions follow
Correct Answer: Both conclusions follow
Solution : The possible Venn diagram, according to the given statements is as follows –
Let's analyse the conclusions – Conclusion (I): Some aluminiums are irons – From the Venn diagram, it is evident that some parts of the circle representing aluminiums lie inside the
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 $\frac{1}{679}$.
