## Task 3 - 170623

In the turning shop of a company, individual parts are turned from lead rods. Each lead rod produces one individual part.

The swarf obtained from the production of every 6 individual parts can be melted down to make one lead rod. (Any smaller amount of swarf is insufficient for this purpose.)

What is the maximum number of individual parts that can be produced in total from 36 rods according to this process?
From 36 raw blanks, 36 individual parts are initially obtained; the waste chips from each 6 raw blanks can then produce another raw blank, meaning that from the waste chips of 36 raw blanks, 6 new raw blanks can be made.

From these, another 6 individual parts can be produced. The chips that fall off during this process can produce one more raw blank. If one more individual part is made from it, chips will fall off again, but these cannot be used (after melting) to produce another raw blank.

Therefore, the total number of individual parts is $36+6+1=43$.
