Problem Analysis

We are given that a master and his apprentice worked for three days. On the first day, they made 384 parts. This is 150 parts less than the second day and twice as many as the third day. We need to find the total number of parts made by the master and his apprentice in three days.

Solution

Let's break down the information given: - On the first day, they made 384 parts. - The second day had 150 parts more than the first day. - The third day had half the number of parts made on the first day.

To find the number of parts made on the second day, we add 150 to the number of parts made on the first day. To find the number of parts made on the third day, we divide the number of parts made on the first day by 2.

Let's calculate the number of parts made on each day:

- First day: 384 parts - Second day: 384 + 150 = 534 parts - Third day: 384 / 2 = 192 parts

To find the total number of parts made in three days, we add up the number of parts made on each day:

384 + 534 + 192 = 1110 parts

Therefore, the master and his apprentice made 1110 parts in three days.

Answer

The master and his apprentice made 1110 parts in three days.
