According to the number that each person can do, it is concluded that one person can do three C's, so nine B's and 15 A's are needed to match.

And one person can do four B's and eight A's, so nine B's need 9/4 people to do it. Similarly, 15/8 people need to do it. So that is to say, if you do it together, the proportion of people who do A, B and C is 15/8: 9/4: 1.

And people must be integers, each item can be multiplied by 8, and the ratio is 15: 18: 8.

The total is 4 1.

So we need 15 as A, 18 as B and 8 as C.

Or:

Solution: If X components are made of C, it is necessary to make 5x components of A and 3x components of B, and arrange X people to do C, X people to do A and X people to do B,

x+x+x=4 1，

x=4 1，

x \ = 4 1 \

x=24，

To make component C, we need to arrange: ×24=8 (people),

To be a human element, we need to arrange: ×24= 15 (human),

The preparation of component B needs to be arranged as follows: ×24= 18 (person),

A: Arrange 65,438+05 people, 65,438+08 people and 8 people to make three components A, B and C, so that the three components can be matched.
