Match the items of List - I with those of List - II and indicate the correct code : Codes : (a) (b) (c) (d)List - I List - II (a) Substitute Goods (i) Negative Cross Elasticity (b) Complementary Goods (ii) Low Price Elasticity (c) Giffen Goods (iii) Positive Cross Elasticity (d) High Income Group Consumption Goods (iv) Positive Price Elasticity
(iii) (i) (iv) (ii)
(a) Substitute goods (tea and coffee): a rise in the price of one raises the demand for the other, so the cross elasticity is positive. (a) matches (iii) Positive Cross Elasticity.
(b) Complementary goods (car and petrol): a rise in the price of one reduces the demand for the other, so the cross elasticity is negative. (b) matches (i) Negative Cross Elasticity.
(c) Giffen goods are inferior goods whose quantity demanded rises when their price rises, so price and quantity move in the same direction and price elasticity is positive. (c) matches (iv) Positive Price Elasticity.
(d) Goods consumed by high income groups take a small share of their budget, so price changes hardly affect the quantity they buy; demand is price inelastic. (d) matches (ii) Low Price Elasticity.
The matching is (a)-(iii), (b)-(i), (c)-(iv), (d)-(ii).
Hence, the answer is (iii) (i) (iv) (ii).
The following is the demand function in the small market :
\(Q = 50 - 5P\)
Where ‘Q’ denotes quantity in physical units and ‘P’ denotes price of the commodity. At price ₹ 5, the point price elasticity of demand would be :
