To find,
Max. marks
ATQ,
Let,
Total marks be x marks
Then,
Required marks to pass=30%*x
150=30/100*x
150*10/3=x
50*10=x
x=500 marks

Hope this helps you!

Answer 2

Answer:

500marks

Step-by-step explanation:

a student needs to score at least 30% marks (given)

a student gets 135 marks and fails by 15 marks (given)

$30\% = 135 + 15 = 150marks$

to find the value of 100%

$\frac{150}{30} \times 100$

refer the attachment

=500 marks

solution by assuming x

let the value of 100% marks be X

30% of X = 150 marks

$\frac{30}{100} \times x = 150$

$x = 150 \times \frac{10}{3}$

$x = 50 \times 10$

$x = 500$
