If demand curve for an electric tooth brush is D=25000−7P and supply curve is S=10000+8P, find the equilibrium Price?

  1. A
    Rs 150
  2. B
    Rs 1000
  3. C
    Rs 400
  4. D
    Rs 50

Solution & Step-by-step Explanation

At market equilibrium, the quantity demanded equals the quantity supplied (D=S).
Given:

D=25000−7P
S=10000+8P
Equating the two expressions:

25000−7P=10000+8P
Rearranging the terms to solve for P:

25000−10000=8P+7P
15000=15P
P=
15
15000
​

P=1000
Thus, the equilibrium price is Rs 1000.
