The question asks us to determine how much a seller should pay if they purchase 8 durians, given that they paid 3 sheets of Rp100,000 (total Rp300,000) for 12 durians and received Rp30,000 in change.

Step-by-step solution:

1. Determine the total price for 12 durians:

   • The seller paid Rp300,000 and received Rp30,000 in change.
   • Therefore, the total price for 12 durians is: $300,000 - 30,000 = 270,000$ So, the total price for 12 durians is Rp270,000.

2. Calculate the price per durian:

   • To find the price of one durian, divide the total price by 12: $\frac{270,000}{12} = 22,500$ Each durian costs Rp22,500.

3. Calculate the total cost for 8 durians:

   • If the seller buys 8 durians, the total cost will be: $8 \times 22,500 = 180,000$ The total cost for 8 durians is Rp180,000.

Answer:

The seller should pay Rp180,000 for 8 durians, which corresponds to option D.
