The coefficient of PES is 3. A seller supplies 30 units of this commodity at a price of 10rs per unit. How much quantity of it will he supply when its price rises by 12%.

Answer»

Solution :
PES `=(DeltaQ)/(DeltaP)xx(P)/(Q)`
`3=(DeltaQ)/(1.2)xx(10)/(30)`
`DeltaQ=(108)/(10)=10.8`
As PRICE increases,quantity suppliedalso increases as per law of SUPPLY
New Quantity =INITIAL Quantity+DeltaQ =30+10.8=40.8`
