Question

Successive discounts of 10%, 12% and 15% amount to a single discount of :

• A. 32.68%
• B. 35.25%
• C. 36.68%
• D. 37.59%
• E. None of these

Answer 1

The correct option is A

32.68%

Let marked price be Rs.100.

Then,S.P.=85% of 88% of 90% of Rs. $\left(\frac{85}{100}\times \frac{88}{100}\times \frac{90}{100}\times 100\right)$=Rs.67.32

$\therefore$ Single discount =(100-67.32)% = 32.68%.
