marks more than the other. If marks of student who got more marks is 52% of the sum of the marks of both of them, then find the marks obtained by them.Solution
Let total marks obtained by both of them is x and y respectively. x – y = 10 And, x = 0.52 × (x + y) x = 0.52 × (10 + y + y) x = 0.52 × (10 + 2y) x = 5.2 + 1.04y 10 + y = 5.2 + 1.04y 0.04y = 4.8 y = 120 x = 120 + 10 = 130
