Price elasticity of supply is 2.5. At a price of Rs.5/unit its quantity supplied is 300 units. Calculate the quantity supplied at a price of Rs.4/unit
`{:(" P 5"),(" P"_(1)" 4,"),(ulbar(Delta"P -1")):}" "{:("Q 300"),("Q"_(1)" "?),(ulbar(DeltaQ" ?")):}` `P.e_(S)=(P)/(Q)xx(DeltaQ)/(DeltaP)" or "2.5=(5)/(300)xx(DeltaQ)/(-1)` `DeltaQ=-150` `DeltaQ=Q_(1)-Q" or "-150=Q_(1)-300` `Q_(1)=150`

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`

When price of a good is Rs. 7 per unit a consumer busy 12 units . When price fails to Rs. 6 per unit he spends Rs. 72 on the good . Calculate price el
`{:(" Price"," Demand"),(" " 7," "12),(" "6," "(72)/(6)=12):}` `E_(P)=(P)/(Q)xx(DeltaQ)/(DeltaP)` `=(7)/(12)xx(0)/(-1)=0` The demand curve is parallel to the y- axis.

When the price of a commodity falls from Rs. 10 per unit to Rs. 9 per unit , its quantity supplied falls by 20 percent . Calculate its price elesticit
Percent change in price `=(-1)/(10)xx100=-10%` Percent change in supply =-20% `E_(s) =("Percentage change in supply")/("Percentage change in price")=(-20)/(-10)=2`

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.
