Study the given information carefully and answer the following questions. Four students i.e. A, B, C and D appeared for written and practical examinations of year 2019-20 The information given below is known: Total Maximum Marks = Maximum marks of written Exam + Maximum marks of practical Exam Total Maximum weighted score = Maximum marks in written exam xx weighted % + Maximum marks in practical exam xx weighted % Weighted score = Marks obtained in written exam xx weighted % + Marks obtained in practical exam xx weighted % Weighted percentage of written exam is 60% and that of practical exam is 40%. Also, maximum marks of written exam is 80 and that of practical exam is 60 It is given that: Total weighted score of A is 52 . Total weighted score of B is 52 and B obtained 55 marks in practical exam. C obtained 50 marks in practical exam. Marks obtained by D in written examination is 70 and D obtained 75% marks in practical exam. If ratio of marks scored by a 5th student X in the written exam and practical exam is 5 : 3 and the weighted score of X is 52.5, then what is the sum of the marks scored by X in written and practical exams?
