What do you mean by complements? Give examples of two goods which are complements of each other.
Complements refer to goods which are consumed together. These are goods that are used in combination with each other, where the consumption of one good is related to the consumption of another good.
Examples of complementary goods include tea and sugar, shoes and socks, and pen and ink. These goods are used together, so the demand for one affects the demand for the other.
The relationship between complements is such that the demand for a good moves in the opposite direction of the price of its complementary goods. For instance, if the price of sugar increases, the demand for tea is likely to decrease, and if the price of sugar decreases, the demand for tea is likely to increase.
Explanation
This answer is based on Section 2.4.4 of the NCERT textbook which defines complementary goods as those consumed together. The textbook provides clear examples (tea and sugar, shoes and socks, pen and ink) and explains the inverse relationship between the price of a complementary good and demand for the related good. A 3-mark answer requires definition, examples, and explanation of the price-demand relationship.
