Question

suresh obtained 70% marks in examination . if he obtained 525 marks . find the maximum marks

Answer 1

let the maximum marks be x
According to the question:
70% of x = 525
70/100 * x = 525
x = 525*100/70
x = 750
Therefore the maximum marks are 750

Answer 2

Question: Suresh obtained 70% marks in examination. If he obtained 525 marks. Find out the maximum marks.

========================================================

Answer:

Maximum mark is total mark, which is 100%.

Suresh obtained marks (in percentage) = 70% of total mark

70% of total mark = 525

Let the total mark be $x$.

Then, 

$70$% of $x$ $=525$

=>  $70$% $*$ $x=525$

=>  $\frac{70}{100}*x=525$

=>  $\frac{70x}{100}=525$

=>  $\frac{7x}{10}=525$

=>  $7x=525*10$

=>  $7x=5250$

=>  $x= \frac{5250}{7}$

=>  $x=750$


So, $x$ is equal to 750.
Therefore, the total mark or, maximum mark is 750.

Final answer: The maximum mark is 750.

ANOTHER WAY :

Suresh obtained marks (in percentage) = 70% of total mark

70% of total mark = 525

The remaining percentage is 30%.

100% - 70% = 30%

Let the total mark be $x$.

Then, 

$525+30$% of $x=x$

=>   $525+30$% $*$ $x=x$

=>   $525+ \frac{30x}{100}=x$

=>   $525=x- \frac{30x}{100}$

=>   $x- \frac{30x}{100}=525$

=>   $\frac{100x-30x}{100}=525$

=>   $\frac{70x}{100}=525$

=>   $70x=525*100$

=>   $70x=52500$

=>  $x= \frac{52500}{70}$

=>  $x= \frac{5250}{7}$

=>  $x=750$

So, $x$ is equal to 750.
Therefore, the total mark or, maximum mark is 750.

Final answer: The maximum mark is 750.
