The problem of workers processing parts
Suppose there are x workers in this group, and the average number of parts processed by the rest workers is y, and the countable equation is 3/5×X×50+2/5×X×y=40X. It is found that the average number of parts processed by other workers is 25.
Story books and science books.
There are 1 00 story books and popular science books in the corner of Class Six (1), and 3/4 of the known popular science books are less than 5/8 of the story books 13. Suppose there are x story books, then there are (100-X) science and technology books. The countable equation is 5/8× x-(100-x )× 3/4 =13. There are 64 story books and 36 science books.
