If 24 marks is 60 %, then full marks is 40
<em><u>Solution:</u></em>
Given that 24 marks is 60 %
We are asked to find the full marks
Let the full marks be "x"
So out of "x" marks, he has got 24 marks
Therefore,
60 % of full marks = 24
60 % of x = 24
Therefore, full marks is 40
<h3><u>Method 2:</u></h3>If 60 % is 24, then we have to find what is 100 %
60 % = 24
100 % = x
This forms a proportion, So we can solve the sum by cross multiplying
Thus full marks is 40
For this case we have the following expression:
Applying distributive property to the terms within parentheses we have:
We add similar terms on both sides of equality considering that:
Equal signs are added and the same sign is placed.
Different signs are subtracted and the major sign is placed.
We add 7.5x to both sides of equality:
We subtract 72 from both sides of equality:
We divide between 3 on both sides of equality
