With rise in price from ₹ 8 to ₹ 14 , total expenditure on the commodity rises by 40% and becomes ₹1,120. Calculate price elasticity of demand. Also, indicate whether demand. Also, indicate whether demand is elastic or inelastic.

from the following data, calculate price elasticity of demand.

When price of a good falls from ₹ 15 per unit to ₹ 12 per unit. Its demand rises by 25 percent. Calculate price elasticity of demand.

when price of a good falls from ₹ 5 to ₹ 3 per unit, its demand rises by 40 % . Calculate its price elasticity of demand.

Price of a commodity fall from ₹ 20 to ₹ 15 per unit. Its demand rises from 600 units to 750 units. Calculate its price elasticity of demand.

As price of a 5 per cent fall in the price of a good, its demand rises by 12 % find out the price elasticity of demand.

The Percentage change in demand is three times the percentage change in price. If original demand was 30 units at the price of ₹ 7 per unit, then calculate the price elasticity of demand, given price increased by 10% . Indicate whether the demand is elastic or not. Also calculate the new quantity demanded.

Price of a good rises by per cent but there is no effect on demand of the good due to this price rise. Calculate price elasticity of demand.
