introduction to micro economics section 1 MCQ Questions & Answers Detailed Explanation

Answer: (a)

In economics, the demand curve is the graph depicting the relationship between the price of a certain commodity and the amount of it that consumers are willing and able to purchase at that given price. A change in the price of the commodity leads to a movement along the demand curve without shifting it.

In simple words, the increase or decrease in the price of a commodity only causes contraction or extension of demand (increase causes contraction while decrease cause extension).

An increase or decrease in demand only occurs only when there is a change in other determinants of demand, other than the price of the commodity.

So when the price of the commodity changes, the demand curve does not shift; however, when any other determinant of demand changes, the demand curve shifts either rightward or leftward.

The Theory of Economic Problem states that scarcity exists in the sense that only finite and insufficient resources are available to satisfy the needs and desires of all human beings.

Break-even is the point of balance between making either a profit or a loss. In economics & business, specifically cost accounting, the break-even point (BEP) is the point at which cost or expenses and revenue are equal: there is no net loss or gain, and one has “broken even”.

A profit or a loss has not been made, although opportunity costs have been “paid”, and capital has received the risk-adjusted, expected return.
