Question

passing marks in an examination is 40% a student gets to 290 marks he falls shot by 30 marks find the total marks of the examination​

Answer 1

Answer:

800

Step-by-step explanation:

290 +30 = 320

320 = x× 40/100

320 = x 4/10

320 = x 2/5

320 × 5/2 = x

1600/2 = x

= 800

Answer 2

As per question,

It is given that,

Passing marks in an examination is 40%.

As a student gets 290 marks he fails the exams by 30 marks

Let the total mark of examination = 100x.

As the passing mark is 40% of total mark.

So, passing mark $=40\%\:of\:100x = 40x$

From question,

As he get 290 and fails by 30.

So, for passing the exam he needs a total of $(290+30) = 320$ marks.

So,

$40x = 320\\=>x = \frac{320}{40} = 8$

So, passing mark of the exam will be $=100x = (100\times 8) = 800$.
