Correct Answer: 7

Solution : $7\left(\cot 11^{\circ} \cot 13^{\circ} \cot 19^{\circ} \cot 29^{\circ} \cot 61^{\circ} \cot 71^{\circ} \cot 77^{\circ} \cot 79^{\circ}\right)$
$=7\left(\cot 11^{\circ} \cot 13^{\circ} \cot 19^{\circ} \cot 29^{\circ} \cot (90^{\circ}-29^{\circ}) \cot (90^\circ-19^\circ) \cot (90^\circ-13^\circ) \cot (90^\circ-11^\circ)\right)$
$=7\left(\cot 11^{\circ} \cot 13^{\circ} \cot 19^{\circ} \cot 29^{\circ} \tan 29^{\circ} \tan 19^{\circ} \tan

Correct Answer: 15

Solution : Given, $3x-2y=3$ and $xy=9$
Consider, $3x-2y=3$
Squaring both sides, we get,
$(3x-2y)^2=3^2$
⇒ $9x^2+4y^2-12xy=9$
Adding $24xy$ on the both sides, we get,
⇒ $9x^2+4y^2-12xy+24xy=9+24xy$
⇒ $(3x+2y)^2+12xy=9+24xy$
⇒ $(3x+2y)^2=9+24\times 9$
⇒ $(3x+2y)^2=9+219$
⇒ $(3x+2y)=\sqrt{225}$
⇒ $(3x+2y)=15$
Hence, the correct answer is 15.
