Veracity on the Market

There is some Veracity on the idea that there is a relationship between SUPPLY, DEMAND and PRICE.

Supply and demand are basically the two sides of a same coin. Supply is what the producers are willing and able to sell in the market at the given price at the given period of time. Demand is what consumers are willing and able to purchase in the market at the given period and given price.
You are in a mixed economy where major decisions are taken by the forces of demand and supply. It's not that difficult, very simple to understand ,supply and demand both are two aspects which we all have to judge in order to take major decisions for the welfare of economy as a whole.
As supply increases in the market due to some reason and demand remains unchanged them the prices of those goods and services will fall and this happening would also force demand to increase. Similarly when demand changes it also affects supply in the same manner. So the relationship of supply and demand is quite easy to understand, whatever changes in one thing ,it would affect other aspects as well . Means you can't think of single aspect without thinking it's affect on other aspect. Both supply and demand go into setting the price of something, but they can be independent of each other.

In short, you are usually more interested in what the changes are to the supply or the demand for a product are. Usually, you will not be able to know in advance what the changes to supply or demand are really going to be because different world events can impact both unexpectedly.
