Option 1: 12
Option 2: 7
Option 3: 2
Option 4: 5
Correct Answer: 7
Solution : $8 \cot \theta = 6$ $\therefore \cot \theta = \frac{6}{8}$ Now, $\frac{(\sin \theta+\cos \theta)}{(\sin \theta-\cos \theta)}$ Dividing numerator and denominator by $\sin \theta$ $=\frac{(1+\cot \theta )}{(1-\cot \theta)}$ $=\frac{1+ \frac{6}{8}}{1- \frac{6}{8}}$ $=\frac{\frac{14}{8}}{\frac{2}{8}}$ $=\frac{14}{2}$ $=7$ Hence, the correct answer is 7.
