Question
A scored 35% marks and failed by 40 marks whereas B
scored 55% marks, which was 80 more than the passing marks of the examination. Find the total marks of the examination.Solution
Let the total available marks in the examination be 100x. Marks scored by A = 35% of 100x= 35x Marks scored by B = 55% of 100x= 55x According to question, => 35x + 40 = 55x – 80 => 20x = 120 => x = 6 Total marks of the examination = 100x = 600
