Answer 2

Answer:

Total marks in examination = 1000 marks

Step-by-step explanation:

Given,

Passing marks = 180

Sheela got = 15 % of total marks

She failed by 30 marks

Let the total marks be x

So,

Sheela got = 15 % of x

= $\frac{15}{100} * x$

Dividing both numerator and denominator by 5

= $\frac{3}{20} * x$

= $\frac{3x}{20}$

Now,

Marks obtained + Marks by which she failed = Passing Marks'

$\frac{3x}{20}$   + 30 = 180

Subtracting 30 from both sides ,

$\frac{3x}{20}$   + 30 - 30 = 180 - 30

$\frac{3x}{20}$  = 150

Multiplying 20 on both sides,

$\frac{3x}{20}$  * 20 = 150 * 20

3 x = 3000

Dividing by 3 on both side,

x = 3000 / 3

x = 1000

Hence,

Total marks in examination = 1000 marks
