Suppose that initial demand 100 units. With rise in price by ₹5 , the quantity demanded decreases by 5 units . Elasticity of demand is 1.2 find out initial price.
( Hint. Use negative sign in the formula )

With the rise in price, quantity demanded for the goods falls and it is known as decrease in demand.
