Question
Marks scored by A and B in a test are in the ratio 14:9
respectively. If B had scored 8 more marks, then marks scored by A would be 20% 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 14x and 9x respectively. Difference between the marks scored by A and B = 14x – 9x = 5x According to question, => (9x + 8) × 1.2 = 14x => 10.8x + 9.6 = 14x => 3.2x = 9.6 => x = 3 Required difference = 5x = 15
