Directions: The table below gives the percentage of marks obtained by 6 students in 6 subjects in an examination. Answer the following question based on the data given in the table. The numbers in brackets are the maximum marks in each subject. Student Subjects (Max. Marks) Physics (120) Biology (120) Maths (120) Geology (120) Economics (120) English (120) A 70 75 70 65 60 70 B 80 70 75 60 50 75 C 75 72 71 70 60 65 D 60 70 65 55 60 70 E 70 75 65 50 55 60 F 65 70 60 65 50 60

Find the average marks obtained by a student in Economics and Physics, respectively.

To find the average Physics marks, calculate the mean of the given percentages: 70, 80, 75, 60, 70, and 65. Adding these six values gives a sum of 420, and dividing by 6 gives an average of 70 percent. Since the maximum marks for Physics are 120, the average marks obtained are 70 percent of 120, which equals 84. Repeating this for Economics, the sum of the percentages (60, 50, 60, 60, 55, 50) is 335, yielding an average of 335 divided by 6, which is approximately 55.833 percent. Multiplying this percentage by the maximum marks of 120 gives an average of 67.16, which rounds to 67. The correct values are 67 and 84.
