Answer 2

Correct Question: The cost of substance A is Rs.40 per mole and of B is Rs.80 per mole. What reasons can you provide for B to be more costly than A?

Explanation:

→ According to the Supply curve when the supply of a substance increases, the price of the substance goes down. Whereas when the supply of a substance decreases, the price of the substance increases.

→ The cost of substance B is more as compared to the cost of substance A. As the price of a substance is inversely proportional to its supply therefore it can be said that the supply of substance A is higher as compared to the supply of substance B.

→ The following can be the reasons for more supply of substance A as compared to substance B, thus reducing its cost:

(1.) Substance A might be more abundant in nature as compared to Substance B.

(2.) Substance A is found in an area from where it is easier to supply it for further processing. For example, an area with better transportation facilities.

(3.) Substance A might be easier to manufacture or process in the factories, thus reducing the cost of production.
