The supply curve of comodity 'B' passes through the origin and makes an angle of `60^(@)`. When its price rises by 40% its quantiy supplied rises by 10 units. Calculate its original supply.

Explanation

`E_(s)= ("Percentage Change in Supply")/(" Percentage change in Price")`
`1= ("Percentage Change in Supply")/(40)`
Percentage change Change in Supply = 40%
we know : Percentage change in Supply `= (DeltaQ)/(Q) xx 100`
`40 = (10)/(Q) xx 100` i.e., Q= 25 units
Orinignal Supply = 25 units
