70/100 * x = 525
x = 525*100/70
x = 750
Therefore the maximum marks are 750

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.
