Show answer & explanation
Correct answer: C
Explanation
The correct answer is option 3 i.e. 8.5.
Calculations:
Discount after two successive discounts = 20 + 15 - (300/100) = 32%
Price with 32% discount = 850 × 68/100 = 578
According to the question;
⇒ 578 - 578 × x/100 = 528.87
⇒ (1 - x/100) = 528.87/578
⇒ (1 - x/100) = 0.915
⇒ x/100 = 1 - 0.915
⇒ x = 0.085 × 100
⇒ x = 8.5
