An electronic store owner allows two successive discounts of 20% and 25% on each item. The store has a reward points scheme which enables a customer to get free shopping worth ₹0.10 on every 1 reward point credited to the customer’s account on previous purchases from the store. A customer decides to buy a laptop that is marked at ₹72,000. What will be its net selling price if he has 2850 reward points to his credit?

To calculate the net selling price of the laptop after applying the successive discounts and using the reward points, follow these steps:

1. Apply the first discount of 20%:

– Discount Amount = 20% of ₹72,000 = 0.20 × 72,000 = ₹14,400

– Price after First Discount = ₹72,000 – ₹14,400 = ₹57,600

2. Apply the second discount of 25%:

– Discount Amount = 25% of ₹57,600 = 0.25 × 57,600 = ₹14,400

– Price after Second Discount = ₹57,600 – ₹14,400 = ₹43,200

3. Calculate the value of the reward points:

– Each reward point is worth ₹0.10.
– Total Reward Points Value = 2850 × ₹0.10 = ₹285

4. Calculate the net selling price:

– Net Selling Price = Price after Second Discount – Total Reward Points Value

– Net Selling Price = ₹43,200 – ₹285 = ₹42,915

Therefore, the net selling price of the laptop after applying the discounts and using the reward points is ₹42,915.
