The problem you uploaded is asking for the percentage discount on the purchase of a shirt, given the following information:

- Danis buys two pairs of pants and a shirt.
- The original price of each pair of pants is Rp 150,000, and the discount on the pants is 80%.
- The price of the shirt is Rp 120,000.
- Danis pays Rp 350,000 and receives Rp 36,000 in change.

We need to determine the percentage discount on the shirt.

### Step-by-Step Solution:

1. **Discount on pants**:
   - The original price of each pair of pants is Rp 150,000.
   - The discount on each pair of pants is 80%, so the price after the discount is:
     \[
     \text{Discounted price of each pair of pants} = 150,000 \times (1 - 0.80) = 150,000 \times 0.20 = 30,000
     \]
   - Danis buys 2 pairs of pants, so the total cost for the pants is:
     \[
     \text{Total cost for pants} = 30,000 \times 2 = 60,000
     \]

2. **Total payment made**:
   - Danis pays Rp 350,000 and receives Rp 36,000 in change. Therefore, the actual amount he spent is:
     \[
     \text{Total spent} = 350,000 - 36,000 = 314,000
     \]

3. **Cost of the shirt after discount**:
   - The total cost of the pants is Rp 60,000, so the cost of the shirt after the discount can be found by subtracting the cost of the pants from the total spent:
     \[
     \text{Cost of shirt after discount} = 314,000 - 60,000 = 254,000
     \]

4. **Discount on the shirt**:
   - The original price of the shirt is Rp 120,000. Let \( x \) be the percentage discount on the shirt. The price of the shirt after the discount is:
     \[
     120,000 \times (1 - \frac{x}{100}) = 254,000
     \]
   - Simplifying this equation:
     \[
     120,000 \times (1 - \frac{x}{100}) = 120,000 - 120,000 \times \frac{x}{100} = 254,000
     \]
     Solving for \( x \), we get the percentage discount.

Let me now calculate the exact percentage.It seems there was an error in the previous step. Upon reviewing, I made a miscalculation. The **correct approach** should involve isolating the calculation of the shirt's discount from the total paid amount, considering the correct total.

I will correct the method and recheck the solution. Let's break it down and solve this again.It appears I misinterpreted the calculation in trying to find the cost structure. Upon review, I realize that the total expenses and original problem need to be approached differently. I'll reassess the steps to refine the explanation and correct the interpretation to avoid error.

Danis membeli dua potong celana dan sebuah baju di sebuah toko. Toko tersebut memberikan diskon untuk setiap celana dan baju yang dibeli. Harga celana Rp 150.000,00 dengan diskon 80% dan harga baju Rp 120.000,00.
