उत्तर
Those goods that can be consumed in place of other goods are called substitute goods. Example: Tea and coffee are goods that can be substitutes for each other. If the price of tea increases, then the demand for tea will decrease and people will substitute coffee for tea, which will increase the demand for coffee.
The demand for a good moves in the same direction as the price of its substitutes.
Price of tea (PT) increases →Demand for tea (DT) decreases →Demand for coffee (DC) increases.
