The alloy is made of tin. 5 parts of tin account for 2 of the same parts of lead. How many grams of tin are in a piece of lead that has 210 grams less lead than tin?

According to the condition of the problem, the alloy contains 5 parts of tin and 2 parts of lead.

Let’s calculate the difference between the number of parts of tin and lead:

5 – 2 = 3.

Also, according to the condition, it is known that lead is 210 g less than tin, that is, 210 g falls to 3 parts, since in the lead alloy there is less lead by 3 parts. Thus, we find how many grams are in one part:

210: 3 = 70 (g).

Let’s calculate how much tin is in the alloy, if there are 5 parts of it, and one part has 70 g:

5 * 70 = 350 (g).

Answer: Tin in an alloy 350 grams.
