A student scored 80% in Mathematics and 70% in Science. If the maximum marks for each subject are 200, what is the total percentage of marks obtained by the student?
75%
76%
77%
78%
Total marks obtained = (80/100)*200 + (70/100)*200 = 160 + 140 = 300. Total maximum marks = 200 + 200 = 400. Percentage = (300/400)*100 = 75%.

Q
Q: A student scored 80% in Mathematics and 70% in Science. If the maximum marks for each subject are 200, what is the total percentage of marks obtained by the student?
Solution: Total marks obtained = (80/100)*200 + (70/100)*200 = 160 + 140 = 300. Total maximum marks = 200 + 200 = 400. Percentage = (300/400)*100 = 75%.
Steps: 5
Step 1: Calculate the marks obtained in Mathematics. The student scored 80% in Mathematics out of a maximum of 200 marks. So, marks obtained in Mathematics = (80/100) * 200.
Step 2: Calculate the marks obtained in Science. The student scored 70% in Science out of a maximum of 200 marks. So, marks obtained in Science = (70/100) * 200.
Step 3: Add the marks obtained in both subjects to find the total marks obtained. Total marks obtained = marks in Mathematics + marks in Science.
Step 4: Calculate the total maximum marks. Since each subject has a maximum of 200 marks, total maximum marks = 200 + 200.
Step 5: Calculate the percentage of marks obtained by the student. Percentage = (Total marks obtained / Total maximum marks) * 100.
