A student scored 80% in Mathematics and 70% in Science. If the maximum marks for each subject are 100, what is the percentage of marks obtained by the student in both subjects combined?
Correct Answer: 75%
Step 1: Understand that the student scored 80% in Mathematics and 70% in Science.
Step 2: Know that the maximum marks for each subject are 100.
Step 3: Calculate the marks obtained in Mathematics: 80% of 100 = 80 marks.
Step 4: Calculate the marks obtained in Science: 70% of 100 = 70 marks.
Step 5: Add the marks obtained in both subjects: 80 marks (Math) + 70 marks (Science) = 150 marks.
Step 6: Calculate the total maximum marks for both subjects: 100 (Math) + 100 (Science) = 200 marks.
Step 7: Calculate the percentage of marks obtained: (Total marks obtained / Total maximum marks) * 100 = (150 / 200) * 100.
Step 8: Simplify the calculation: (150 / 200) = 0.75, then multiply by 100 to get 75%.
