Study the following information carefully and answer the given questions. In a school 4 students A, B, C and D appeared in an English examination which is consist of 15 short and 4 long questions are asked. Each of short question carry 5 marks and each of long questions carry 10 mark and for a spelling error 0.5 mark is deducted. For not attempting a question, zero marks is awarded. In the English exam, A answered (x + 6) short questions, x long questions and did (2x + 10) spelling errors. Ratio of number of spelling errors made by A and B is 8 : 3. Total marks scored by D is 86. Ratio of short and long questions answered by B In the English exam is 5 : 1 and he scored total 102 marks. C scored 35 marks more in short questions than long questions except spelling errors and the number of spelling errors made by C is equal to the difference of the number of spelling errors made by A and B. Number of short questions answered by D is average of that answered by A and B. Percentage of number of long questions answered among all the question answered by D is 20% . Average of the number of spelling errors made by all four students A, B, C and D is 10. Each student attempts integral number of short as well as long questions. A student E, scored 30 marks more than that by C, whose total marks is more than that by A but less than that by D. If the number of spelling errors made by E are 10 more than that by C, then the total marks scored by C is what percent less than that by E?
