A question from GRE book says: A candidate who gets 30 percent marks in an examination fails by 30 marks,but another candidate who gets 42 percent marks get 42 more marks than necessary for passing.Find the maximum number of marks and total necessary for passing. I started with it by: Let passing marks =x Then for Student1; (x-30) Student 2;(x+42) But what should I equate it to get them compared and find 'x' and then total marks?
