Let the total number of these parts be x.

The equation is as follows: (x/3+24)+(x/3-12)+60 = x.

Do the math. It's simple.

The second question:

Note: This topic is prone to ambiguity, and the questioner is extremely abnormal.

The original planned output value of a workshop is X.

X * 2 10%+( 150-X)* 220% = 323

The actual completion value of Workshop A is calculated as X * 2 10%.

The value of workshop b, hehe, is simple.

The third question:

1, because the original price of both parties is the same.

Let the original price be x

X * 100/70 = X * 100/90+200

Substitute x into the original equation and do it yourself.

On the basis of the first question, I looked at it myself. Note: 80 yuan is deducted for every full 200 yuan, so: 400 MINUS 160 600 MINUS 240. ...

You know
