Correct Answer: B


Solution : For the first condition,
We know that two successive discounts of $a$% and $b$% are equivalent to $(a+b-\frac{a×b}{100})\%$
So, two successive discounts of 10% and 15% are equivalent to,
$(10+15-\frac{10×15}{100})=23.5$%
For the second condition,
So, discount = $\frac{7-5}{7}×100=28.57$%
So, the scheme which has the maximum discount is B.
Hence, the correct answer is B.
