Let there be two consumers A and B in the market for a good. Their demand functions are given below. Find out the market demand function:
(i) `d_(A)(P) =20-P` for `ple20` and `d_(A)(P)=0` if `P gt 20`
(ii) `d_(B)(P)=30-2P` for `P le 15` and `d_(B)(P)=0` if `P gt 15`

Let three be two consumers in the market. Their demand functions are given. Calculate market dd. d_(1)(P)=30-P for Ple30 and d_(1)(P)=0 for P lt 30 d_(2)(P)=50-P for Ple50 and d_(2)(P) =0 for Plt50

Suppose there are two consumers in the market for a good and their demand functions are as follows : ** d_(1)(p)=20-p for any price less than or equal to 15, and d_(1)(p) =0 at ant price greater than 15. ** d_(2)(p) = 30-2p for any price less than or equal to 15 and d_(1)(p)=0 at any price greater than 15. Find out the market demand function.

If the demand function is D=(p+6)/(p-3) Find the elasticity of demand at p = 4.

The demand function of a good is Q_(d) = 600-25P . Find out the level of demand when price will be (i) Rs. 5, (ii) Rs. 10.
