Answer:
The correct answer is "16".
Explanation:
The given question seems to be incomplete. Please find the attachment of the full query.
According to the question,
The supply per producer when there are overall 10 producers,
⇒ [tex]P(\frac{Y}{10} )=10+(\frac{Y}{200} )[/tex]
or,
⇒    [tex]Y=200P-2000[/tex]
The consumption per producer when there are overall 100 producers,
⇒ [tex]P(\frac{x}{100} )= 40-(\frac{2x}{100} )[/tex]
or,
⇒      [tex]x = 2000-50 P[/tex]
At equilibrium,
⇒ [tex]200P-2000=2000-50P[/tex]
On adding "2000" both sides, we get
⇒ [tex]200P-2000+2000=2000-50P+2000[/tex]
⇒             [tex]200P=4000-50P[/tex]
             [tex]250P=4000[/tex]
                [tex]P=\frac{4000}{250}[/tex]
                  [tex]=16[/tex]
