Correct Answer: $-\frac{3}{5}$

Solution : Given: $\tan\alpha=2$
We know that $\sec^{2}\alpha = 1 + \tan^{2}\alpha$ and $\operatorname{cosec}^{2}\alpha = 1 + \cot^{2}\alpha$
Since $\tan\alpha = 2$, we have $\sec^{2}\alpha = 1 + (2)^{2} = 5$
Also, $\cot\alpha = \frac{1}{\tan\alpha} = \frac{1}{2}$
So $\operatorname{cosec}^{2}\alpha = 1 + (\frac{1}{2})^{2} = \frac{5}{4}$
Putting the

Correct Answer: $\frac{13}{15}$

Solution : $\left[\frac{1}{5}+\left\{\frac{1}{6}\right.\right.$ of $\left.\left.\left(\frac{42}{35} \div \frac{6}{25}\right)–\left(\frac{2}{7} \times \frac{6}{5} \div \frac{18}{42}\right)\right\}+\frac{19}{30}\right]$
$=\left[\frac{1}{5}+\left\{\frac{1}{6}\right.\right.$ of $\left.\left.\left(\frac{42}{35} \times \frac{25}{6}\right)–\left(\frac{2}{7} \times \frac{6}{5} \times \frac{42}{18}\right)\right\}+\frac{19}{30}\right]$
$=[\frac{1}{5}+(\frac{1}{6}\times 5–\frac{4}{5})+\frac{19}{30}]$
$=[\frac{1}{5}+(\frac{5}{6}–\frac{4}{5})+\frac{19}{30}]$
$=[\frac{1}{5}+\frac{1}{30}+\frac{19}{30}]$
$=\frac{26}{30}$
$=\frac{13}{15}$
Hence, the correct answer is $\frac{13}{15}$.

Correct Answer: 34.56%

Solution : Let the radius of the original circle = $r$
So, the Area of the original circle = $\pi r^2$
 Radius of circle after 16% increase = $r+\frac{16r}{100} =1.16r$
Area of new circle = $\pi \times 1.16^2 = 1.3456r^2$
Percentage increase in area 
$\frac{1.3456\pi r^2- \pi

Correct Answer: 19 cm

Solution :
Let the line BD intersect the bigger circle at point C.
Join AC.
OD $\perp$ BD ⇒ OD $\perp$ BC
So, BD = DC
⇒ D is the midpoint of BC.
Also, O is the midpoint of AB.
In $\triangle$BAC, O is the midpoint

Correct Answer: 1

Solution : The correct answer is the first option. 

"The gold" should be replaced with "Gold" as articles never come before a material noun so the article "the" should be removed. "Gold" is correctly used as a noun referring to the precious metal.

Therefore, the correct statement

Correct Answer: Trading blocks

Solution : The Correct Answer is Trading blocks

Trading blocs are merely associations of nations that set the rules for international commerce. An example of an intergovernmental agreement is a trade bloc, which is frequently a component of a regional intergovernmental organization. In a trade bloc,

Correct Answer: 64°

Solution :
Since opposite angles of a rhombus are equal
So, $\angle$ADC = $\angle$ABC = 52°
Also, $\angle$DAC = $\angle$DCA = $x$ (say) [since AD = DC]
In $\triangle$ ADC,
$\angle$ADC + $\angle$DAC + $\angle$DCA = 180°
⇒ $x+x+52°$ = 180°
⇒ $x$ = 64°
⇒ $\angle$DCA
