Option 1: 44%
Option 2: 52%
Option 3: 45%
Option 4: 50%
Correct Answer: 44%
Solution :
Given: Two successive discounts of 30% and 20%.
Single equivalent discount = $(a+b-\frac{a×b}{100})\%$, where $a=30\%$ and $b=20\%$ are successive discounts.
$=30+20-\frac{30\times 20}{100}$
$=50-6$
$=44\%$
Hence, the correct answer is 44%.
