Two students appeared in an exam and one secured 18
marks more than the other. If marks of the student who got more marks is 58% of the sum of the marks of both of them, then find the marks obtained by them.Solution
ATQ, Let total marks obtained by both of them be x and y respectively. x β y = 18 And, x = 0.58Γ(x+y) x = 0.58Γ(18+y+y) x = 0.58Γ(18+2y) x =10.44+1.16y 18+y = 10.44+1.16y 0.16y = 7.56 y = 47.25 x = 47.25+18 = 65.25
