Calculate the ` P.e_(D)` for a commodity when its price increases by 25% and quantity demanded falls from 150 units to 120 units.

Calculate the price elasticity of demand for a commodity when its price increase by 25% and quantity demanded falls from 150 units to units.

P.e_(D) for a good is (-) 0.4. if its price increases by 5% by what percentage will its demand fall ?

P.e_(D) of a good is (-)1. Calculate the % change in price that will raise the demand from 20 units to 20 units.

P.e_(D) of a good is (-)1. when its price falls by one rupee, its demand rises from 16 units to 18 units. Calculate the price before change.

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 1080 units . Calculate its price elasticity of demand . Is its demand inelastic ? Given reasons for your answer.

The coefficient of price elasticity of demand for a commodity is 0.2. when price was ₹ 10 per unit. The quantity demanded was 40 units. If the price falls to ₹ 5 per unit, how much will be its quantity demanded ?

the price of a commondity is ₹ 12 per unit and its quantity demanded is 500 units. When price rises by ₹ 3 per unit, its quantity demanded falls by 150 units. Calculate its price elasticity of demand. Is demand elastic ?

As price of a commodity increases from ₹ 4 per unit to ₹ 5 per unit, demand falls from 20 units to 10 units. Find out the elasticity of demand.
