Correct Answer: INR 312.50


Solution : Single equivalent discount = $(a+b-\frac{a×b}{100}$)%, where $a=15\%$ and $b=25\%$ are successive discounts.
$=15+25-\frac{15\times 25}{100}=40-3.75=36.25\%$
The required difference $=\frac{36.25-30}{100}\times 5000=\frac{6.25}{100}\times 5000=$ INR 312.50
Hence, the correct answer is INR 312.50.
