It has been said in the conditions that the purchased beans weigh 10kg and the basket weighs 0.5 kg, so the weight of beans can be ignored first, because the current weight-the original weight can omit the weight of beans, while10.55-10 = 0.55, that is, the 0.5 kg basket weighs 0.05 kg.

From this, we can get the actual bean weight of 10 kg beans on the scale =110.

So the actual weight of beans is10 ÷11/kloc-0 ≈ 9 kg.
