Question
Marks scored by A and B in a test are in the ratio 13:5
respectively. If B had scored 5 more marks, then marks scored by A would be 30% more than that of B. Find the difference between actual marks scored by A and B.Solution
Let actual marks scored by A and B be 13x and 5x respectively. Difference between the marks scored by A and B = 13x – 5x = 8x According to question, => (5x + 5) × 1.3 = 13x => 6.5x + 6.5 = 13x => 6.5x = 6.5 => x = 1 Required difference = 8x = 8
