Question

a student got 30% marks and failed by 108 marks second student got 52% marks which is 24 marks more than required marks what are total marks required in examination​

Answer 1

Answer:

Let the total marks be T and passing marks be P

Scored 30% of total and failed by 45 means passing marks minus 30% of total is 45

P - 0.3T = 45 → equation 1

Scored 42% of total and is 45 marks above the passing marks

0.42T = 45 + P →equation 2

Solving the two equations we get, total marks as 750 and passing marks as 270
