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`

At Rs.12/unit, quantity supplied of a commodity is 500 units. When its price riese to Rs.15/unit, its quantity supplied rises to 650 units. Calculate
`{:(" P 12"),(" P"_(1)" 15"),(ulbar(DeltaP" 3")):}" "{:("Q 500"),("Q"_(1)" 650"),(ulbar(DeltaQ" 150")):}" "P.e_(S)=(P)/(Q)xx(DeltaQ)/(DeltaP)=(12)/(500)xx(150)/(3)=1.2` Yes, supply is elastic as it is greater than one.

If in a system unit of mass is 5kg, unit of length is 10m and unit of time as 5sec, then what will be the value of 1 unit energy in new system.
`[E]=[ML^(2)T^(-2)]=(5)` `=(10)^(2)(5)^(2)=20` joules

At a price of Rs. 50 per unit the quantity demanded of a commodity is 1000 units . When its price falls by 10 percent , its quantity demanded rises to
`E_(P)=(P)/(Q)xx(DeltaQ)/(DeltaP)=(50)/(1000)xx(80)/(-5)=(-)(4)/(5)=(-)0.8` The demand is inelastic because the absolute value of clasticity is less than 1 (sign ignored).

The price of a commodity is Rs.12 per unit and its quantity supplied is 500 units. When its price rises to Rs. 15 per unit , its quantity supplied ris
`E_(s)=(P)/(Q_(s))xx(DeltaQ_(s))/(DeltaP)=(12)/(500)xx(150)/(3)=1.2` Yes, the supply is elastic because `E_(s) gt 1`
