Problem Analysis

We are given that a locksmith and his apprentice manufactured a total of 42 parts. The locksmith works 5 times faster than the apprentice. We need to determine how many parts the apprentice made.

Solution

Let's assume that the apprentice made x parts. Since the locksmith works 5 times faster, he made 5x parts. The total number of parts is the sum of the parts made by the locksmith and the apprentice, which is x + 5x = 42.

Simplifying the equation, we have 6x = 42. Dividing both sides by 6, we find that x, the number of parts made by the apprentice, is equal to 7.

Therefore, the apprentice made 7 parts.

Answer

The apprentice made 7 parts.
