Commodities A and B have equal price elasticity of demand . The demand of X rises from 100 units to 150 units due to a 20 per cent fall in its price. Calculate the percentage fall in demand of Y if its price rises by 8 per cent.

The price elasticity of demand of good x is half the price elasticity of demand of good y. A 25% rise in price of good y reduces its demand from 400 to 300 units. Percentage change in demand of good x when its price falls from ₹10 to ₹8 per units.
