In the given figure rasy incident on an interface would converge 10cm below the interface if they continues to move in straight lines without bending. But due to refraction, the rays will bend and meet some where else. Find the distance of meeting point of refracted rasy below the interface, assuming the rays to be making small angles with the normal to the interface.

The bar graph shows average marks scored in a 100 marks History exam by students of 7 divisions of Standard X. Study the diagram and answer the following questions. If all students of Division C lost 10 marks each for cheating in the test then their new average marks would decrease by how much?

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?
