2. Solution Steps

To find the cost per block for each set, we need to divide the total cost by the number of blocks.

For Set A:

Cost per block $= \frac{\text{Total Cost}}{\text{Number of Blocks}} = \frac{12}{60} = 0.20$ euros per block.

For Set B:

Cost per block $= \frac{\text{Total Cost}}{\text{Number of Blocks}} = \frac{28}{150} \approx 0.1867$ euros per block.

Comparing the cost per block for Set A and Set B:

Set A: $0.20$ euros per block

Set B: $0.1867$ euros per block

Since $0.1867 < 0.20$, Set B is cheaper per block.

3. Final Answer

Set B is cheaper per block.
