Given: Selling price of the Tablet = Rs. 15,300 Discount% = 15% Formula Used: MP = SP × {100/(100 - Discount%)} where, MP = Marked Price SP = Selling Price Calculation: To find the actual price we need to find the Marked Price. So, MP = SP × {100/(100 - Discount%)} ⇒ MP = 15,300 × {100/(100 - 15)} ⇒ MP = 15,300 × (100/85) ⇒ MP = (900 × 100)/5 ⇒ MP = 90,000/5 ⇒ MP = 18,000 ∴ The actual price of the Tablet is Rs. 18,000. Shortcut Trick Let the Actual price or MP ≡ 100 So, at a 15% discount, SP ≡ 85 Now MP/SP = 100/85 ⇒ MP = (100/85) × 15,300 ⇒ MP = 18,000 ∴ The actual price of the Tablet is Rs. 18,000. Mistake Points Do not take Rs. 15,300 as the Cost Price (as it will lead to the wrong answer) while solving the question as it is the Selling Price. Because the tablet is being sold to Arpit by Flipkart at Rs. 15,300. Confusion Points The language of the question is such that, it seems Rs. 15,300 is the Cost Price. But observe carefully, Arpit paid Rs. 15,300 and bought that tablet at a 15% discount. It means that the Tablet was sold to Arpit at Rs. 15,300. Since we have to find the Actual Price, it means we have to find the Marked Price.
