Option 1: 26%

Option 2: 28%

Option 3: 30%

Option 4: 32%

Team Careers360 · Accepted Answer

Correct Answer: 28%

Solution : Single equivalent discount = $(a+b-\frac{a×b}{100}$)%, where $a$% and $b$% are successive discounts.
So, the single discount of two successive discounts of 10% and 20%
$ = 10 + 20 - \frac{(10 imes 20) }{ 100} $
$=30-2$
$= 28\%$
Hence, the correct answer is 28%.
