Salav consists of 19 parts aluminum and 2 parts magnesium. What is the mass of an alloy if it contains 34 kg less magnesium than aluminum?

To solve the problem, you first need to determine the difference between the parts of aluminum and magnesium.

Let us subtract from the number of parts of aluminum the number of parts of magnesium.

19 – 2 = 17 pieces.

Find the weight of one piece.

To do this, we divide the difference in weight by the difference in the number of parts.

34/17 = 2 kg.

We find the total number of parts.

To do this, we summarize the number of parts of aluminum and magnesium.

19 + 2 = 21 pieces.

Find the weight of the alloy.

To do this, we multiply the sum of the parts by the weight of one of them.

21 * 2 = 42 kg.

Answer: The weight of the alloy is 42 kg.
