A consumer buys 80 units of a good at a price of Rs. 4 per unit . When the price falls , he buys 100 If price elasticity of demand is (-) 1, find out
`E_(p)=(P)/(Q)xx(DeltaQ)/(DeltaP)` `(-)1=(40)/(80)xx(20)/(DeltaP)` `(-)1=(1)/(DeltaP)` `DeltaP=-1` New price `=P+DeltaP=4+(-1)=Rs.3`.

Price elasticity of demand of a good is (-) 2. At a price of Rs. 10 per unit 40 units of this good are bought . How units will be bought at a price of
`E_(P)=(P)/(Q)xx(DeltaQ)/(DeltaP)` `(-)2=(10)/(40)xx(DeltaQ)/(1)` `(-)80=10DeltaQ` `DeltaQ=-8` New `Q=Q+DeltaQ=40+(-8)=32` units.

When price of a good falls by 10 percent , its quantity demanded rises from 40 units to 50 units. Calculate price elasticity of demand by the percenta
`E_(P)=(%" change in Qty . Demanded")/(% " change in price")=((10)/(40)xx10)/(-10)=(25)/(-10)=(-)2.5`

Due to a 10 percent rise in the price of a commodity , its quantity supplied rises from 400 units to 450 units. Calculate its price elasticity of supp
`E_(s)=(%"Change in supply")/(% "Change in price ")=((50)/(400)xx100)/(10)=((25)/(2))/(10)=(25)/(10)=1.25` Supply is elastic because `E_(s) gt 1`.

The price elasticity of supply of a commodity is 2. When its price falls from Rs. 10 to Rs. 8 per unit, its quantity supplied falls by 500 units . Cal
`E_(s)=(P)/(Q)xx(DeltaQ)/(DeltaP),2=(10)/(Q)xx(-500)/(-2),4Q=5000,Q=1250` Supply at `Rs 8=Q+ DeltaQ=1250 +(-500)=750` units.
