In an examination if a person get 20% of the marks then it is fail by ...
Given information:
- Person A gets 20% marks and fails by 30 marks.
- Person B gets 30% marks and passes with 30 marks more than passing marks.
To find: Total marks and passing marks.
Let's assume that the total marks are 'x' and the passing marks are 'y'.
Calculations for Person A:
- Person A gets 20% marks, which is 0.2x.
- According to the question, Person A fails by 30 marks, so his actual marks must be 30 less than the passing marks.
- Therefore, 0.2x = y - 30.
Calculations for Person B:
- Person B gets 30% marks, which is 0.3x.
- According to the question, Person B passes with 30 marks more than the passing marks, so his actual marks must be 30 more than the passing marks.
- Therefore, 0.3x = y + 30.
Now we have two equations with two variables:
0.2x = y - 30
0.3x = y + 30
Solving these equations, we get:
x = 600
y = 150
Hence, the total marks are 600 and the passing marks are 150, which is option 'A'.
- Person A gets 20% marks and fails by 30 marks.
- Person B gets 30% marks and passes with 30 marks more than passing marks.
To find: Total marks and passing marks.
Let's assume that the total marks are 'x' and the passing marks are 'y'.

Calculations for Person B:
- Person B gets 30% marks, which is 0.3x.
- According to the question, Person B passes with 30 marks more than the passing marks, so his actual marks must be 30 more than the passing marks.
- Therefore, 0.3x = y + 30.
Now we have two equations with two variables:
0.2x = y - 30
0.3x = y + 30
Solving these equations, we get:
x = 600
y = 150
Hence, the total marks are 600 and the passing marks are 150, which is option 'A'.
