A given % fall in P will cause a smaller % rise in Q so that total revenue (P times Q) falls.
A4) Scenario 1 To find optimum price, We use the demand function Quantity = 5024.58 -136.62(Price of oil ) + 117.41(Price of competitor’s products) – 0.2823(Per capita income of consumers) + 7.87 (Promotional Expenditure of Mustard oil) Total Revenue can be maximized at a point at which there is unit elasticity i.e. PED=1 Total Revenue =P*Q Q= 25521.268 -136.62P ------(1) (Here p is price of the oil, Substituted all values to get this equation) Multiplying P on both sides of equation (1) to get total revenue Total Revenue= 25521.268 P-136.62(P 2 ) First derivative of TR with respect to P d TR/d P = 25521.268 -136.62(2P) We know that when TR is maximum, the slope is zero, hence equalizing the above to zero P=93.40 Hence, Price = 93.40 Competitor’s price =109.14 Income Per Capital= 7620.6015 (after 1% increase) Promotional Expenditure = 1247.31 Total Revenue= Q*P = 12760*93.40 = 1191873.66
Scenario 2 To find optimum price, We use the demand function Quantity = 5024.58 -136.62(Price of oil ) + 117.41(Price of competitor’s products) – 0.2823(Per capita income of consumers) + 7.87 (Promotional Expenditure of Mustard oil) 6% increase in the competitor’s price Revised competitor’s price = 115.6884 (After 6 % interest) Q=26290.304-136.62 P Revenue is maximized , When Elasticity with respect to price is unity or 1 Therefore, E= slope *(P/Q) 1=136.62 *(P/Q) P=Q / 136.62 ------------(1) Substituting the value of P in the demand equation, 2Q=26290.304 Q=13145.15 Now Substituting Q in Equation 1 P=13145.15/136.62 P=96.21 Total Revenue= Q*P =13145.15*96.21 =1264785.75 Comparing Both the Scenario , We find increase in competitor price benefits Hind Oil as the Net Revenue of its product Increases Total Revenue = 1264785.75 Differential Revenue= 72,912.09 When the competitor increases the price, the company shall benefit if we decrease the price as total revenue increases .
