Answer:

135 g

Explanation:

The 15 potatoes have a mean mass of 136 g, so their total mass is 15 × 136 = 2040 g.

Similarly, the 3 potatoes have a mean mass of 130 g, so their total mass is 3 × 130 = 390 g.

Therefore, the 18 potatoes have a total mass of 2040 + 390 = 2430 g. So their mean mass is 2430 / 18 = 135 g.
