Question

B. The price of Samosa today is $3, and the quantity demanded is 1000. Next year the price drops to $2 and the quantity demanded rises to 2000.​

Answer 1

If the price goes up, the quantity demanded goes down (but demand itself stays the same). If the price decreases, quantity demanded increases. This is the Law of Demand. On a graph, an inverse relationship is represented by a downward sloping line from left to right.
