please answer this step by step ​

Answer 1

Answer:

Given that, student who gets 20% marks fails by 10% marks.

So, the passing percentage = 20% + 10% = 30%

Another student who gets 42% marks gets 12 marks more than the passing marks.

So, he gets 12 % more marks than passing percentage.

Let x be maximum marks.

12% of x = 12

x = 100

So, maximum marks = 100
