A shopkeeper allows three different discounts on marked price of an item. He allows 10%, 15% and 20% discount. The selling price of an item after discount is Rs.6120. Cost price of an item is 50% less than the marked price of an item. Find the cost price of an item.
1. Rs.13000
2. Rs.15000
3. Rs.5000
4. Rs.4000
5. Rs.10000

Answer 1

Correct Answer - Option 3 : Rs.5000

Given:

Let cost price of an item be Rs.a

⇒ Marked price of an item = a × 100/50 = Rs.2a

⇒ Selling price of an item = 2a × 90/100 × 85/100 × 80/100

⇒ 6120 = 2a × 90/100 × 85/100 × 80/100

⇒ a = 5000

∴ The cost price of an item is Rs.5000.
