Question : A dealer gives 10%, 20%, and 30% successive discounts on an item. What is the single equivalent discount on the item?

Option 1: 54.8%

Option 2: 52.8%

Option 3: 47.6%

Option 4: 49.6%

Team Careers360 · Accepted Answer

Correct Answer: 49.6%

Solution : We know:
Equivalent single discount = $(a+b-\frac{a×b}{100}$)%,
Where $a,b$ are successive discounts.
So, $20+10-\frac{20 imes 10}{100}=28$%
Now again $a = 28$% and $b = 30$%
So, $28+30-\frac{28 imes 30}{100}=49.6$%
Hence, the correct answer is 49.6%.
