Bronze contains (by weight) 41 parts of copper, 8 parts of tin and 1 part of zinc.

Bronze contains (by weight) 41 parts of copper, 8 parts of tin and 1 part of zinc. What is the mass of a piece of bronze if it contains 132 g less tin than copper?

Let’s solve this task by action. 1) 41 – 8 = 33 parts – there are so fewer parts of tin than copper. 2) 132: 33 = 4 grams – the mass of one part of the alloy. 3) 41 * 4 = 164 grams – the mass of copper in a piece of bronze; 4) 8 * 4 = 32 grams – the mass of tin in a piece of bronze; 5) 1 * 4 = 4 grams – the mass of zinc in a piece of bronze; 6) 164 + 32 + 4 = 196 + 4 = 200 grams – the mass of the entire piece of bronze, which consists of copper, tin, zinc.
Answer: 200 grams.
