Question : Simplify the following expression: $\frac{1-\sin A}{\cos A}+\frac{\cos A}{1-\sin A}$
Option 1: $2 \cos A$
Option 2: $2 \tan A$
Option 3: $2 \sec A$
Option 4: $2 \sin A$
Correct Answer: $2 \sec A$
Solution : $\frac{1-\sin A}{\cos A}+\frac{\cos A}{1-\sin A}$ $=\frac{(1-\sin A)^2+\cos^2A}{\cos A(1-\sin A)}$ $=\frac{1+\sin^2 A-2\sin A+\cos^2A}{\cos A(1-\sin A)}$ $=\frac{1+1 -2\sin A}{\cos A(1-\sin A)}$ $=\frac{2 -2\sin A}{\cos A(1-\sin A)}$ $=\frac{2(1 -\sin A)}{\cos A(1-\sin A)}$ $=\frac{2}{\cos A}$ $=2\sec A$ Hence, the correct answer is $2\sec A$.

Option 1: Loss 1%
Option 2: Loss 0.1%
Option 3: Gain 0.1%
Option 4: Gain 1%
Correct Answer: Loss 1%
Solution : Marked price, $MP$ = INR 550 Cost price, $CP=\frac{MP\times 100}{(100+10)}$ = $\frac{550\times 100}{(110)}$ = INR 500 Selling price after 10% discount on marked price, $SP = \frac{550\times (100-10)}{100}$ = $\frac{550\times 90}{100}$ = INR 495 Now, loss percentage = $\frac{(CP-SP)}{CP}\times 100$ = $\frac{(CP-SP)}{CP}\times 100$ =
