A(n) <u>natural</u> join returns not only the rows matching the join condition (that is, rows with matching values in the common columns) but also the rows with unmatched values.
<h3><u>What is a "natural join"?</u></h3>
By default, natural joins are natural inner joins, however, they can also be natural left, right, and full outer joins. The main distinction between an inner join and a natural join is that an inner join has a join condition that is specified explicitly, whereas a natural join's conditions are determined by matching all pairs of columns in the tables that have the same name and compatible data types, which makes natural joins equijoin because the join condition is equal between common columns.

Answer:
Given:
Cold water faucet fills the sink in 4 minutes.
Both faucets fills the sink in 3 minutes.
Let us assume that "t" be the time it takes hot water faucet in order to fill the sink.
Therefore;
<em>Rate for hot water faucet fills the sink = 
= 
</em>
<em>Rate at which cold water faucet fills the sink = = 
</em>
When both faucets are used , the rate at which they fill the sink is given as :
<em> + = 
</em>
On solving the above equation, we get :
<em>
</em>
<em>∴ 
</em>
<em>Therefore, it takes 12 minutes for the hot water faucet to fill the sink.</em>
