Correct Answer: 57.81%


Solution : Single equivalent discount = $(a+b–\frac{a×b}{100}$)%, where $a$% and $b$% are successive discounts.
Single discount equivalent to successive discounts of 25% and 25%
$=25+ 25 - \frac{625}{100} = 43.75$%
Single discount equivalent to successive discounts of 43.75% and 25%
$=43.75 + 25-\frac{43.75×25}{100} =68.75 - \frac{1093.75}{100} = 57.81$%
Hence, the correct answer is 57.81%.
