Quantity supplied of a commodity increases by 50% when its price rises from 8rs per unit to 10rs per unit. Calculate elasticity of supply.

SOLUTION :
Percentage change in price `= (DELTAP)/(P)xx100=(2)/(8)xx100=25%`
ES=`("Percentage Change in supply")/("Percentage Change in Price")=(50%)/(25%)=2`
`ES=2` (Supply is elastic as `ES gt 1`)
ES is ALWAYS positive due to direct relationship between price and quantity supplied.
