A scored 30% marks and failed by 40 marks whereas B scored 60% marks, which was 80 more than the passing marks of the examination. Find the total marks of the examination.
Let the total available marks in the examination be 100x. Marks scored by A = 30% of 100x = 30x Marks scored by B = 60% of 100x = 60x According to question, => 30x + 40 = 60x – 80 => 30x = 120 => x = 4 Total marks of the examination = 100x = 400
