Question : Two successive price decreases of 20% and 30% of an article are equivalent to a single price decrease of:
Option 1: 50%
Option 2: 44%
Option 3: 25%
Option 4: 40%
Correct Answer: 44%
Solution :
Single equivalent discount = $(a+b–\frac{a×b}{100}$)%, where $a$% and $b$% are successive discounts.
⇒ Single equivalent discount = $20+30-\frac{20×30}{100}=50-6=44$%
Hence, the correct answer is 44%.
