Correct Answer: (19, 216, 25)

Solution : Given:
(12, 125, 17); ( 8, 27, 11)

Subtract the first number from the third number, and then cube the resultant, to get the second number –
⇒ (12, 125, 17)→(17 – 12)³ = 5³ = 125
⇒ (8, 27, 11)→(11

Correct Answer: 34

Solution : Given:
Raju ranks 10th from the top and Ravi ranks 21st from the bottom. There are 3 students between Raju and Ravi.

Total number of students = 10 (Raju's rank) + 21 (Ravi's rank) + 3 (students between them)
Total number of students = 34

Correct Answer: Lion

Solution : Given:
Nest : Bird :: Den : ? 

Like, birds live in nests.
Similarly, lions live in dens.

Hence, the second option is correct.

Correct Answer: $2(1+\sec A)$

Solution : Given: 
$\frac{\cos A}{1+\sin A}+\frac{1+\sin A}{\cos A}+2$
= $\frac{\cos^2A+1+\sin A+\sin A+\sin^2A}{(1+\sin A)(\cos A)}+2$
= $\frac{2+2\sin A}{(1+\sin A)(\cos A)}+2$
= $\frac{2(1+\sin A)}{(1+\sin A)(\cos A)}+2$
= $\frac{2}{\cos A}+2$
= $2\sec A+2$
= $2(1+\sec A)$
Hence, the correct answer is $2(1+\sec A)$.

Correct Answer: the egg

Solution : The correct choice is the first option.

The error in the original segment lies in the article used before "egg". The correct article is "an" instead of "the". This is because when referring to a singular, countable object like

Solution : The third option is the correct choice. 

Passive voice is the voice in which the object experiences an action rather than the person who performs the action. Hence, the object in the active voice becomes

Correct Answer: 21

Solution : 508 + $x$ = perfect square
The perfect square nearest to 508 is 529 = 23²
$\therefore x$ = 529 – 508 = 21
Hence, the correct answer is 21.

Correct Answer: $2$

Solution : Given: $\sqrt{x}=\sqrt{3}-\sqrt{5}$
By squaring both the sides, we get,
$x=3+5-2\sqrt{15}$
⇒ $x-8=-2\sqrt{15}$
Again, squaring both the sides, we get,
$x^2-16x+64=60$
⇒ $x^2-16x+4=0$
$\therefore x^2-16x+6=2$
Hence, the correct answer is $2$.
