Question
In an examination, two students participated, where one
student scored 15 marks higher than the other. If the higher-scoring student's marks constitute 52% of their combined total marks, determine the individual scores of both students.Solution
Let total marks obtained by both of them is x and y respectively. x – y = 15 And, x = 0.52 × (x + y) x = 0.52 × (15 + y + y) x = 0.52 × (15 + 2y) x = 7.8 + 1.04y 15 + y = 7.8 + 1.04y 0.04y = 7.2 y = 180 x = 180 + 15 = 195
