Question 1044563
.
20% of the total number of pupils in a class is 6.How many pupils are there in the class altogether?
~~~~~~~~~~~~~~~~~~~~~~~~~


<U>Solution 1</U>


<pre>
20% is {{{1/5}}}: {{{20/100}}} = {{{1/5}}}.

So, {{{1/5}}} of the total number of pupils in the class is 6.
Then the total number of pupils in the class is 5 times 6: 5*6 = 30.

<U>Answer</U>.  There are 30 pupils in the class.
</pre>


<U>Solution 2</U>


<pre>
Let x be the total number of pupils in the class.

Then you are given that {{{(20/100)*x}}} = 6.

Cancel the factor 20 in the numerator and the denominator in the left side.

You will get  {{{(1/5)*x}}} = 6.

Multiply by 5 both sides. You will get x = 5*6 = 30.

The same answer.
