The dmeand function of good 'A' is given as: `Q_(A) = 40-5P_(A)`. Calculate its price elasticity when price rises from ₹ 4 to ₹ 6.

The demand funcation of Commodity 'X' is given as : Q_(x)= 20 - 2P_(x) . Calculate its price elasticity of demand when price falls from ₹ 5 to ₹3.

Given that demand function is Q_(d) = 100-5P (i) Calculate demand at price of Rs. 4 (ii) Calculate demand at price of Rs. 6

The demand for good rises by 20 percent as a result of fall in its price elasticity of demand is (-) 0.8 . Calculate the percentage fall in price.

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

When price of a good falls by 50 percent, its demand rises by 60 percent . Calculate its price ealsticity of demand.

The price elasticity of demand of good X si double the price elasticity of demand of Good Y . A 10% rise in the price of good Y results in fall in its demand by 60 units. If original demand of commodity Y was 400, calculate percentage rise in quantity demanded of good X when its when its price falls from ₹ 10 to ₹ 8 per unit.
