Correct Answer: 75%

Solution : Given: Both first and second discounts = 50%
Net discount = $(x+y-\frac{xy}{100})$%, where $x$ and $y$ are two successive discounts.
= $50+50-\frac{\text{50×50}}{100}$
= $100-\frac{\text{2500}}{100}$
= $100-25$
= $75$%
Hence, the correct answer is 75%.

Correct Answer: $\sec A+\tan A$

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