A student obtained 75%, 80% and 85% in three subjects, if the marks of another subject are added then the number cannot be less than ______?
- 70%
- 80%
- 60%
- None of these
Explanation
Let's assume the maximum marks in each subject are 100. Then, the student's total marks in the three subjects are:
75 + 80 + 85 = 240
If the marks of another subject are added, the total marks become:
240 + x (where x is the marks obtained in the fourth subject)
The average percentage cannot be less than 60% because:
- If the student scores 0 in the fourth subject, the total marks would be 240, and the average percentage would be (240/400) x 100% = 60%.
- If the student scores any marks in the fourth subject, the average percentage would be higher than 60%.
