Ram and Nikhil both are dealers of Boeing helicopter. The price of boeing helicopter is Rs. 28000. Ram gives a discount of 10% on the whole, while Nikhil gives a discount of 12% on first Rs 20000 and 8% on the rest Rs. 8000. What is the difference between their selling prices?

Answer

To solve the problem, we need to calculate the selling prices of both Ram and Nikhil after applying their respective discounts and then find the difference between those selling prices.

### Step-by-Step Solution:

1. **Calculate Ram's Selling Price:**
- The original price of the helicopter = Rs. 28,000.
- Ram gives a discount of 10% on the whole price.
- Discount = 10% of 28,000 = (10/100) * 28,000 = Rs. 2,800.
- Selling Price (SP) for Ram = Original Price - Discount = 28,000 - 2,800 = Rs. 25,200.

2. **Calculate Nikhil's Selling Price:**
- The original price of the helicopter = Rs. 28,000.
- Nikhil gives a discount of 12% on the first Rs. 20,000 and 8% on the remaining Rs. 8,000.
- Discount on the first Rs. 20,000 = 12% of 20,000 = (12/100) * 20,000 = Rs. 2,400.
- Discount on the remaining Rs. 8,000 = 8% of 8,000 = (8/100) * 8,000 = Rs. 640.
- Total Discount for Nikhil = 2,400 + 640 = Rs. 3,040.
- Selling Price (SP) for Nikhil = Original Price - Total Discount = 28,000 - 3,040 = Rs. 24,960.

3. **Calculate the Difference in Selling Prices:**
- Difference = Selling Price of Ram - Selling Price of Nikhil = 25,200 - 24,960 = Rs. 240.

### Final Answer:
The difference between their selling prices is Rs. 240.
