• A. $32.68\%$
• B. $35.28\%$
• C. $36.68\%$
• D. $Noneofthese$

Answer 1

The correct option is A $32.68\%$

Let the marked price is $Rs.100$

Then according to the given condition

$Sellingprice=(\frac{85}{100}\times \frac{88}{100}\times \frac{90}{100}\times 100)=Rs.67.32$

Hence, single discount $=32.68$%
