Correct Answer - Option 1 : 16
Given :
The marked price of the article = Rs.2400
The selling price of the article = Rs.1542.24
Three successive discounts are 15%,10% and x%
Formula used :
Selling price = Marked price - Discount
Calculation :
⇒ 1542.24 = 2400 × (85/100) × (90/100) × (\( { {100-x} \over 100}\))
⇒ 1542.24 = {1836 × (100 - x)}/100
⇒ 154224 = 183600 - 1836x
⇒ 1836x = 29376
⇒ x = 16
∴ The value of 'x' is 16
