The text says:
"2000원짜리 물건을 3개 사는데 10% 할인받았다. 얼마를 지불해야 하는가?"

Let's break this down:
- "2000원짜리 물건" means an item that costs 2000 won.
- "3개 사는데" means buying 3 of them.
- "10% 할인받았다" means you get a 10% discount.
- "얼마를 지불해야 하는가?" means "How much do you have to pay?"

Step 1: Calculate the total price without any discount.
One item costs 2000 won.
You are buying 3 items.
Total price = 2000 × 3 = 6000 won.

Step 2: Calculate the discount amount.
The discount is 10% of the total price.
Discount = 10% of 6000 won.
To find 10%, you can multiply by 0.10.
Discount = 6000 × 0.10 = 600 won.

Step 3: Calculate the final price to pay.
Final price = Total price - Discount
Final price = 6000 - 600 = 5400 won.

Alternatively, you can think of it this way:
If you get a 10% discount, you pay 90% of the original price.
Final price = 90% of 6000 won.
Final price = 6000 × 0.90 = 5400 won.

Both methods give the same result.

Final Answer:
5400 won
