In the plant’s turning shop the final parts are turned from lead billets. A part from one billet. The shaved off chips obtained after 6 parts are produced, can then be melted into an additional billet.
How many final parts can be made in this way from the initial 36 lead billets?
How many final parts can be made in this way from the initial 36 lead billets?
Explanations
Without a thorough consideration of the subtle nuances of the challenge’s rules, one can reason: 36 billets give 36 parts; since the chips of every six billets give one more new billet, then six new billets are formed from the chips of the initial 36 billets. These are 6 more final parts; total 36 + 6 = 42 parts.At the same time, these additional 6 parts would also produce chips sufficient enough for one more billet. Hence, one more final part. Thus, the total number of parts will not be 42, but 43.
