A student scored 75% in Mathematics and 85% in Science. If the total marks in each subject are 200, what is the total percentage?
80%
82%
83%
85%
Total marks obtained = (0.75 * 200) + (0.85 * 200) = 150 + 170 = 320. Total percentage = (320 / 400) * 100 = 80%.

Q
Q: A student scored 75% in Mathematics and 85% in Science. If the total marks in each subject are 200, what is the total percentage?
Solution: Total marks obtained = (0.75 * 200) + (0.85 * 200) = 150 + 170 = 320. Total percentage = (320 / 400) * 100 = 80%.
Steps: 5
Step 1: Calculate the marks obtained in Mathematics. Since the student scored 75%, we find 75% of 200. This is done by multiplying 0.75 by 200.
Step 2: Calculate the marks obtained in Science. The student scored 85%, so we find 85% of 200 by multiplying 0.85 by 200.
Step 3: Add the marks obtained in both subjects together to get the total marks obtained.
Step 4: Calculate the total possible marks. Since there are two subjects and each subject has a total of 200 marks, the total possible marks is 200 + 200.
Step 5: Calculate the total percentage by dividing the total marks obtained by the total possible marks and then multiplying by 100.
